Remarks: Peruvian specimens collected by R. E. Coker and referred 

 by Rathbun (1910) to Pachycheles grossimanus (Guerin) were seen by 

 the present writer at the U. S. National Museum. Those from Bahia 

 de Sechura were found to be P. crinimanus. 



The specific name is derived from the Latin crinis, hair, and 

 manus, hand. 



Range: Peru, from Bahia de Sechura south to Bahia de San 

 Juan. Shore to about 10 fathoms.
