562 THE VOYAGE OF H.M.S. CHALLENGER. 



this subfamily are also placed, with notes of iuterrogation, the genera Carcinornis, A. 

 Costa; On'o, Cocco ; Cliiroimsiis, Cocao ; ^' OniitlwrJiawjiInis," de l^aiaXe. 

 It would have added to. the usefulness of this exceedingly useful work, had there been an 

 Index to this Part, in which the Latin descriptions of so large a number of genera and 

 species are brought together. In regard to the arrangement of the group here adopted, it is 

 not easy to see why some authors should place the Lremodipoda at the head or in the 

 fore-front of the Amphiiaoda, since their structure, however well adapted to their modes 

 of life, points very obviously to degradation, and seems as little as possible typical or 

 representative.

Mr. Chilton gives as the synonymy of Aora typka, Kroyer, the following names, Lalaria 

 lonrjitarsis, Nicolet, Microdeideropus mortoni, Haswell, Bllcrodeuteropus tenuipes, Haswell, 

 Microdeuteropus maridatus, G. M. Thomson. He supports his view by minute details and 

 figures of various specimens, and while giving one description for the female, he describes 

 the other sex thus : — " Male. Three forms, all differing from the female in the character 

 of the first gnathopod, which in each has the meros produced into a long spine reaching 

 about to the end of the carpus. 



"The forms may be distinguished as follows: — 



"1. [Aora typica, Kroyer.) — Easos with a tooth projecting forwards on the anterior margin; 

 carpus longer than the propodos, but of about the same breadth. 



"2. {Microdeuteropus macidatus $, Chilton.) — Carpus longer and broader than propodos; 

 meros with small tuft of seta; on posterior margin. 



"3. {Microdeideropus Mortoni, Haswell.)^ — Carpus longer aud broader than the propodos; 

 meros hollowed anteriorly and with each lateral margin densely fringed with setiB ; dactylos 

 as long as propodos and with two or three tufts of setiK on concave border." 



He repeats an opinion previously expressed that the name Microdeuteropus will have to become 

 a synonym of Aora.
