\\\ the 'Catalogue of New-Zealand Crustacea,' I adduced certain 

 reasons for believing that the Munida subrugosa of White and or 

 Dr. Cunningham is nothing but the mature state of the long-known 

 and exceedingly common Patagonian species Grimothea gregaria, 

 Fabricins. There is considerable variation between younger and 

 older individuals in the length of the external maxillipedes, spines of 

 the antero-lateral angles of the carapace, and of the anterior legs. In 

 the typical specimens of M. subrugosa from the Auckland Islands the 

 rostrum is relatively longer and the antero-lateral marginal spines 

 somewhat less numerous (7-8) than in the Patagonian form ; but 

 the Museum has received adult sjiecimens from New Zealand which 

 agree in all respects with examples from the Magellan Straits. I 

 was formerly inclined to think that the specimens referred by Dana 

 to M. subruyosa belonged to a distinct species ; but the larger series 

 of specimens now before me would seem to show that I was wrong 

 in that conclusion. 



The examples collected by Dr. Coppinger are from Sandy Point 

 (seven females and one male), depth 7-10 fathoms, bottom sand and 

 dead acorn-shells ; Cockle Cove, 2-32 fathoms, bottom mud (male, 

 female, and young); Trinidad Channel, 4 fathoms (four males), bottom 

 sandy (in this locality it was seen in great shoals). 



The males are generally of smaller size than the females.
