same joint; four spines on the posterior margin of the propodus and 

 two on the anterior margin at the distal extremity; the dactylus is 

 serrate along the inner margin. Exopods are present on both first 

 and second gnathopods. The other legs are beset with spines. 



A few specimens, both males 

 b 



and females, were collected by 

 Prof. A. E. Verrill and party 

 at Bailey Bay and Castle Har- 

 bor, Bermudas, in 1898. 



Type specimen from the 

 Bermudas is in the Peabody 

 Museum, Yale University. 

 Cat. No. 3194. 



This species is very closely 

 related to Apseudes intermedium 

 Hansen a but differs in the fol- 

 lowing points: 



1. The first joint of the pe- 

 duncle of the first pair of an- 

 tennae is armed with three 

 spines on the inner margin, 

 and one spine on the outer 

 margin at the distal end. In 

 A. intermedius this joint is 

 unarmed. 



2. In the increased number 

 of joints in the flagella of both 

 pairs of antennae, there being 

 sixteen joints in the flagellum 

 of the first pair of antennas, 

 eight in the secondary append- 

 age, and ten in the flagellum 

 of the second pair of antenna?, 

 while in Doctor Hansen's 

 species the flagellum of 

 the first pair of antennas is 

 composed of seven joints, 

 the secondary appendage of 

 three joints, and the flagellum 



of the second pair of antennae of four joints. 



3. In the much greater length of the uropoda, the inner branch of 

 which in A. propinquus is half the length of the body and composed 

 of thirty-four joints, the outer branch consisting of eleven joints,
