Oil the coxa of the third pair of aiiibulatoiy feet is niinutelj' 

 denticulate. The only additional character in the female is that 

 the squainag of the carapax are more depressed. 



Mr. Miers (1. c, p. 151) remarks: "Only a carapax of this 

 species is known." The carapax referred to, Dana's type, was 

 destroyed in the Chicago fire. The Academy possesses two 

 specimens, male and female, sent b}^ Mr. Andrew Garrett, from 

 Tahiti. 



Genus LEILOPHUS 1 Mi-rs, 1876. {Acanthnpus DeHaan.) 



Meros of external maxillipeds very small, and much narrower 

 than the ischium. 



L. pilimanus Miers ex A. M.-Edw. 



Specimens of this rare species are in the museum of the Academy, 

 from the Sandwich Is. (J. K. Townsend) and Tahiti (A. Garrett). 

 So far as I am aware, the only other specimen, in an^^ collection, 

 is the type in Jardin des Plantes at Paris. The British Museum 

 has no specimens. 



I am unable, either from the poorness of the descriptions, or 

 possible inaccurac}' of the figures, to assign the following species 

 to their proper generic positions.

 Plagusia should have been retained for this section.
