an acute, outward directed spine at the anterolateral angle and three 

 additional lesser but well developed spines along the lateral margin, 

 one precervical and the remaining two postcervical, all subequally 

 spaced. There are seven dorsal spines on the dorsal precervical por- 

 tion, a postorbital pair, behind which there are five spines, forming an 

 irregular transverse row, i.e., a median spine, a submedian pair in line 

 with the postorbital pair and outside and slightly anterior to these 

 another spine on each side of the hepatic region, nearly in line with 

 the first lateral spine. The cervical groove is deep. There are three 

 spines on the postcervical region, a median spine and slightly in ad- 

 vance of this a submedian pair. The transverse rugae and granula- 

 tions are well spaced, the cilia short. There is a submedian pair of 

 spines on the hinder margin of the carapace. The second abdominal 

 segment has six spines, two on either side of the submedian pair ; the 

 third segment has only four, one on each side of the submedian pair ; 

 the fourth segment has only the submedian pair followed by a single 

 median spine. The chelipeds and first three pairs of monodactylar legs 

 are scabrous and spinose.

Genus: MTJNIDOPSIS Whiteaves. 

 Munidopsis simplex A. Milne Edwards. 

 Plate 14. 

 Type: The species was founded upon a series of specimens taken 

 at nine "Blake" stations, at Guadeloupe, Dominica, Martinique and 

 St. Vincent, at depths ranging from 484 to 982 fathoms ; the material 

 was divided between the Paris Museum and the Museum of Compara- 

 tive Zoology. 



Distribution: As above and extended northward by the "Ara's" 

 catch off Miami, Florida, depth 1100 fms. 



Material examined : Eighteen specimens of various sizes dredged 

 in 1100 fathoms, off Miami, Fla., March 31, 1926, by the "Ara."
