290 H. Richardson — Isopods of the Bermudas. 



The lirst thoracic segment is longest. The others are sub-equal 

 with well defined epimera. 



The first five abdominal segments are all coalesced into one seg- 

 ment. The terminal segment is triangular and strongly keeled along 

 the median longitudinal line. 



The inner branches of the uropoda extend beyond the tip of the 

 terminal segment, are broadly oval and fringed with hairs. The 

 outer branches are narrowly oval, about half as wide as the inner 

 branches, and shorter. 



Color light yellow, with numerous black dots. 



About seven specimens were collected by A. E. Verrill and party 

 at Bailey Bay, Bermudas, in 1898. Found at lo\y water in corallines. 

 Others were collected in 1901 at Waterloo, on Castle Harbor, Ber- 

 mudas.

Hab. Castle Harbor, Bermudas, in the cavities of living bathing 

 sponges and in dead coral. Two specimens (No. 33, 34) were 

 taken from the fins of a Hamlet Grouper, in May;* St. Thomas,

* The colors of these, in life, were as follows : Ground color, pale flesh-color ; 

 head and tail, yellowish brown ; seven transverse, irregular bands of yellowish 

 brown, 'those of the middle of the body with two points projecting forward, so 

 as to show a tendency to form two dorsal lines of brown. A. E. V.
