similar to G. rurkola, from the eastern coast. Moreover, the front is nar- 

 rower, deeper, and bent down at a sharper angle than in G. quadrahs, and 

 the merus of the outer maxillipeds is very different in shape from that 

 of G. qiiadrattis or anj other known species.

Gelasimus sp. 



A male specimen of a species of Gelasimus was collected on Chatham 



Island, Galapagos. It agrees with 



the figure of Gelasimus macrodadylus 

 M. Edw. et Luc.,* except in the proportions of the carapace, which is 

 broader (13 X 19 mm.) in the Galapagos specimen.

Excursions iu Madeira and Porto Santo, p. 15, Fig. 2«, 2», 1825. 



Planes, a MS. name of Dr. Leach's, was first published in T. Edward 

 Bowdich's " Excursions in Madeira and Porto Santo, during the Autumn 

 of 1823," London, 1825. In this work Bowdich figured and assigned to 

 this genus the Cancer ndnutus of Linnd, under the name of Fhnes clypcatus. 

 The name Flams was afterwards adopted by Bell, White, and Dana, and 

 more recently by Miers t and Haswell. J But most recent authors have 

 rejected Planes in favor of the later Nautilograpsus of Milne Edwards, § on 

 account of the insufficiency of Bowdich's description. Accepting the 'judi- 

 cious ruling of the American Ornithologists' Union committee on nomen- 

 clature II - that a recognizable published figure affords a valid basis for a 

 generic name -I retain Leach's name for this genus; for Bowdich's figures 



though rudely executed, are unmistakable.
