The eye-stalks are nearly rectangular, a little longer than wide. 

 The anterior margin is slightly concave and under a lens is seen to he 

 armed with denticles. The eye-specks are situated on the outer 



margin just posterior to the rounded por- 

 tion of the distal angle. These specks are 

 much more prominent in this and other 

 species with rectangular eye-stalks than in 

 species with ovoid stalks. The lateral teeth 

 of the anterior margin are a little more ad-, 

 vanced than the middle or rostral tooth, and 

 are placed nearer to the spine of the antero- 

 lateral angle than to this tooth. The margin 

 of the front is sigmoid between the apex of 

 the lateral teeth and the bottom of the ocu-

X i. lar smus. At this point it meets the concave 



line which forms the margin of the rostral 



tooth; at the point where the lines meet there is a very small notch. 



The carapace is broader than long, straight on the median line, and 



strongly curved laterally. 



The carapace of a female from Pensacola, Florida, measures 16.5 ■ 

 mm. long and 19.5 mm. wide. The eye-stalks are -l mm. long and 3.4 

 mm. wide. 



An examination of the stomach of a specimen taken near Morris 

 Cut, opposite Miami, Florida, disclosed the seta- of Annelids, the skin 

 of a very small Synapta with some anchor plates still present, and 

 parts of the flagellse of some small crustacea. 



The type locality of the species called Albimea scutellata by the 

 earlier authors will probably never be known. When Stimpson | 

 erected the genus Lepidopa by separating Alhnnea, he placed in it two \ 

 species from the island of St. Thomas, West Indies. The species with 

 the more rectangular eye-stalks he very properly identified with 

 Alhunea scutellata of Desmarest, Edwards, and others. This identifi- 

 cation he could not have verified nor can we at this time unless the 

 types are extant. As the matter stands the island of St. Thomas can 

 be recognized as the type locality of the species. The specimens in 

 the National Museum do not come from localities nearer St. Thomas 

 than Florida, and it follows that the species here described and figured 

 for Z. scutellata may prove to be new.
