and these have been mentioned in detail by K. H. Barnard. Teeth 

 may be added to the pleon but perhaps lost from the pereon with in- 

 crease in age. 



The urosome folds toward the metasome in such a way that the 

 dorsal teeth of pleonite 4 become nearly congruent with those of 

 pleonal epimeron 3. Dana, therefore, with inferior microscopy, may 

 have thought he was seeing the opposite epimeron projecting from 

 behind and thus illustrated the urosome as dorsally smooth. 



Nicholls had juvenile and adult specimens with dentations com- 

 mencing on pereonite 2 instead of pereonites 5 or 6.

Description. — Male, 22 mm: Pereon, coxae, second articles of 

 pereopods 3-5 and pleonites 1-4 covered with acute or blunt sub- 

 marginal teeth, teeth especially blunt on anterior pereonites, arranged 

 in crude vertical rows on pereonites and pleonites, generally 2 rows 

 except on pereonites 2-6 with 1 row, teeth on coxae, though sparse, 

 generally arranged in rows; pleonite 5 smooth, pleonite 6 with weak 

 dorsolateral tooth on each side; pleonal epimeron 1 with slightly 

 convex posterior margin, posteroventral corner simple but lateral face 

 with weak ridge, epimeron 2 with small posteroventral tooth, epimeron 

 3 with large posteroventral tooth, both epimera with strong lateral 

 ridges, epimeron 3 with large medioposterior tooth in addition to 

 posteroventral tooth; stout rostrum of medium length, lateral sub- 

 planiform base of head produced laterally into large hemispherical 

 ocular bulge, faintly gray pink in alcohol, without supra- and sub- 

 ocular teeth, cheek below eye with deep incision, its borders asym- 

 metrically cuspidiform; articles 1 and 2 of antenna 1 extraordinarily 

 palmate, resembling moose antlers, article 3 short and simple; acces- 

 sory flagellum small, 1-articulate, barrel-like or mammilliform depend- 

 ing on aspect; antenna 2 basally palmate like E. hodgsoni; epistome 

 weak, upper lip rounded below; mandibles broad, incisors serrate, 

 lacinia mobilis on right mandible slender, thin, short, apex broad but 

 obliquely and weakly serrate, palp article 1 scarcely cuspidate distally, 

 article 3 falciform; outer lobes of lower lip not incised; maxillae and 

 maxillipeds, gnathopods, pereopods and uropods like those of E. 

 hodgsoni.
