284 II. Michardson — Isopods of the Bermudas. 



The first pair of legs of the female are much more slender than 

 those of the male. In the male there is a deep excavation on the 

 distal margin of the propodus near the articulation of the dactylus, 

 while in the female this excavation is comparatively small. In the 

 male there is a spine within this excavation and one on the dactylus, 

 both situated at the articulation of the dactjdus and the propodus. 

 Exopods are present on both pairs of gnathopods. All the other 

 legs are very spinulose. 



A few specimens (types) were. collected by A. E. Verrill and party 

 in 1898, at Castle Harbor, Bermudas, and one specimen was collected 

 by G. Brown Goode at the Bermudas in 1876-7. 



Type in Peabody Museum, Yale University. Cat. No. 3222. 



This species has a close resemblance to Parapseades latifrons 

 (Griibe),* but differs in the following characters: in P. goodei the 

 fii'st pair of gnathopods are moi'e robust ; the propodus has a deep 

 excavation near the articulation of the dactylus, within which is a 

 large spine. There is also a spine on the dactj^lus. 



The rostrum is constricted at the base in P. goodei, while in P. 

 latifrons the line is unbroken from the apex of the rostrum to the 

 lateral margin of the head. 



The secondary appendage of the flagellum of the first antennae is 

 composed of four joints in P. goodei while in P. latifrons this 

 appendage is composed of seven joints. The flagellum of the second 

 pair of antennae consists of five joints in P. goodei, while in Grube's 

 species it consists of eight joints.

5 . Body narrow, elongate ; color yellow, with markings of black. 



Head with antero-lateral angles prominent, between which the 

 frontal margin is excavate for the reception of the antennae, the mid- 

 dle being produced in a conspicuous median point. The eyes are 

 situated in the antero-lateral prolongations.
