Lagerberg gives reasons for identifying E. comptus and its varieties with the 

 earlier E. forceps (Milne-Edwards). Nicolet says that his E. gayi is taken along 

 with E. forceps on the coasts of Chile, and has the greatest affinity with it, but 

 differs by the want of spines on the inner feet and the form of the left cheliped, the 

 fingers of which are much more robust. Miss Rathbun, in a List of Species occurring 

 from Panama to the Island of Chiloe, gives all the above-mentioned three specific 

 names separately, but without discussion of their validity. One of the Scotia speci- 

 mens agrees so closely with Nicolet's figure of E. gayi in colouring, size, and features 

 that there can be no doubt of its belonging to the species so named by Nicolet, 

 but the characters on which he relies do not seem to warrant its separation from 

 E. forceps.

Eupagurus modicellus, n. sp. 



Plate XXVId. 



Among the numerous species of this genus I have not been able to find one with 



the combination of characters presented by this little form. The front of the carapace 



has a very blunt median projection and the lateral angles not produced. The eye 



peduncles are long, longer than the front. The second antennae have a slender 



acicle, not denticulate, and a long flagellum, strikingly setose, with some of the setae 



standing out very conspicuously. The endopod of the first maxilla is without a 



flagellum, and all the three pairs of maxillipeds have the exopod flagellate. In the 



third joint of the third maxillipeds the inner margin is finely denticulate, with two of 



the teeth larger than the rest. The right cheliped is much the larger. On the inner 



surface of the hand an elevation extends from the base of the finger transversely to 



the base of the wrist, and another from the tip of the thumb curves gently to meet
