TYPE LOCALITY.—North Atlantic Ocean at 15°26′N, 45°00′W.

DESCRIPTION OF FEMALE.—Body straight, between 2.06 and 2.41 times longer than maximum width, widest at pereonite 5; pereon with ill-defined longitudinal mediodorsal ridge. Cephalon lateral margins converge abruptly in front of eyes to form rostrum which appears truncate in dorsal view; eyes small, subtriangular, facets indistinct. Pereonite 1 longest, anterior margin convex, not recessed to accommodate cephalon; anterolateral margins form into 2 bosses which do not project anteriorly. Pereonites 2–4 subequal in length, pereonite 5 slightly shorter than 4; pereonites 6 and 7 markedly shorter than other pereonites, pereonite 7 about 15–18% length of pereonite 1. Coxae all shorter than pereonites; coxae of pereonites 6 and 7 smaller on one side than other, each with distinct acute dorsal ridge. Pleonites 1–4 subequal in length; pleonite 5 slightly longer, posterior margin with 2 low submedian lobes. Pleotelson nearly as long as wide, lateral margins converging slightly; posterior margin truncate, with median emargination.

Antennule extending to posterior of cephalon, composed of 8 articles, first 3 of which are broad and flattened. Antenna extends to pereonite 1, composed of 9 articles, first 4 of which are broad.

Mandible palp large, folding across anterior to labrum. Maxillule styliform, with 4 terminal spines. Maxilla lateral lobe with about 17 spines, endopod with 8. Maxilliped as in G. impressus, but article 3 with 2–4 spines.

Pereopod 1 short, merus posterior margin not dilated, dactylus extending to middle of carpus; pereopods 2 and 3 longer and less robust than pereopod 1. Pereopods 5–7 basis with posterior expansion well developed, anterior expansion weakly developed; merus with weak anterior expansion.

Pleopods as in G. impressus. Uropod curving medially, endopod slightly longer than exopod, both rami with apices narrowly rounded or acute.

DESCRIPTION OF MALE.—Much shorter than female (38% on average), body approximately rectangular in shape. Antennule with 6 or 7 articles, antenna with 8 or 9. Maxilla lateral lobe with 9 spines, endopod with 6. Maxilliped with 3 stout recurved terminal spines on article 3. Pereopods less robust than in female, pereopods 5–7 basis with weakly developed expansions. Penes elongate, apices lie between pleopod peduncles. Pleopods all simple; appendix masculina absent. Uropods similar to female, exopod slightly longer than endopod.

COLOR.—Anterior of animal and anterior appendages dark brown to nearly black, becoming lighter toward posterior; pleon, pleotelson, and pereopods 6 and 7 virtually without chromatophores.

SIZE.—Ovigerous females between 21.9 and 32.8 mm, one non-ovigerous female was 24.5 mm, males between 8.4 and 12.2 mm.

Cephalon abruptly narrowed anterior to eyes into narrowly rounded triangular rostrum. Eyes small, oval. Pereonite 1 longest, anterior one-third to one-half of lateral margin elevated dorsally into ridge. Lengths of pereonites 2–6 gradually decreasing; pereonite 7 abruptly shorter (relative lengths in percent of pereonites 1–7 of 27.8 mm from Dade Country, Florida: 25.5, 16.0, 15.2, 14.8, 13.2, 10.3, 5.0). Coxae shorter than their pereonites; coxa 7 may have concave dorsal surface and lateral margin elevated into ridge. Pereonite 7 not overlapping any pleonites. Pleonites 1–4 subequal in length; pleonite 5 about twice as long, wider than pleotelson. Pleotelson length/width 0.56–0.71, narrowing slightly posteriorly, lateral margins slightly convex, posterior margin slightly concave.

Antennule composed of 7 articles, article 3 longest. Antenna composed of 7–8 articles, slightly longer than antennule, article 4 longest. Mouthparts as described by Williams and Williams (1985).

Pereopods similar to those of Glossobius impressus; pereopod 3 with longest dactyl.

Pleopods 2–5 with depressions separated by ridges (shown only for endopods in Figure 13l–o). Uropods reaching slightly beyond posterior margin of pleotelson; rami subequal in length or exopod slightly longer.

DESCRIPTION OF MALE.—As described by Williams and Williams (1985).

COLOR.—Head and pereonites 1–4 covered with black chromatophores, sparser on pereonite 4. Pereonites 5–7, pleon, and pleotelson unpigmented.

SIZE.—Females with oostegites ranged in length from 15.1 to 36.9 mm (Figure 14). Western Atlantic specimens are distinctly longer than the Eastern Atlantic specimens. There is a slight overlap between 23 and 25.5 mm, and the second smallest specimen is a 15.5 mm female from Florida.
