This is one of the widely distributed species of the Southern 

 Hemisphere and is very closely allied to its congener M. rugosa of 

 the northern region. A. Milne Edwards (22) points out that it is 

 subject to a not inconsiderable amount of variation, and Professor 

 Henderson, relying on the distribution of spines on the dorsum of the 

 carapace, names a particular variety australicnsis. Mr. Miers invari- 

 ably maintained that M. gregaria, which is found in company with 

 this species in the Falkland region, is only the young of M. siibrn- 

 gosa. General opinion does not, however, favour this view, though 

 it is generally admitted that the only reliable points of distinction 

 are to be found in the maxillipeds. The specimens brought home 

 by the ' Southern Cross ' expedition were numerous and were obtained 

 at the Auckland and the Campbell Islands. None of them, however, 

 show the distinctive features of Professor Henderson's australicnsis, 

 although it is true that the characteristic row of four spines is 

 usually present. These should be sub-equal, but they are not, for 

 the outer ones are extremely minute and not readily seen. Spines 

 on or near the cervical groove may or may not be present and are 

 usually minute. The absence of spines is more noticeable in the 

 Auckland Island specimens, but as these are much smaller it is only 

 to be expected.

Family HIPPOLYTIDAE. 



In dealing with the Crustacea Macrura of the 'Challenger' 

 Expedition Spence Bate (1) sub-divided this family into some ten 

 genera, but these do not appear to be generally accepted. At any 

 rate, a number of new species belonging to the family have been 

 described since the appearance of that report, and in many cases 

 (Milne Edwards, 22) without either reference to Spence Bate's 

 classification, or the essential features upon which it is based. This
