Material examined. — None from the Hancock collections. 

 Remarks. — Pachycheles ackleianus has been taken from sponges and 

 coral heads; it is known to a depth of 37 fathoms. 



Porcellana parrai Guerin from Cuba has not been identified with 

 any of the known Caribbean forms. Since the figure bears some resem- 

 blance to Pachycheles ackleianus, Guerin's species is tentatively placed 

 here. 



The specimens called Pisosoina angustifrons by Boone (1930) are 

 certainly not that species, judging from the description and figure, and 

 should probably be referred to Pachycheles ackleianus.
