MARINE ISOPODS. 



While working in the Johns Hopkins laboratory at Montego Bay, 

 Jamaica, in 1910, Dr. C. B. Wilson and Dr. E. A. Andrews collected a 

 large number of isopods for the United States National Museum. 

 A list of the species is herein given with notes on the variation of 

 Exocorallana tricornis. (Hansen) and Exocorallana quadricornis (Han- 

 sen). The notes on the color markings were furnished by Doctor 

 Wilson. A new species of ExospJiseroma was collected by Doctor 

 Andrews, the description of which is given below.
