AMPHIPODA. CHILTON. <>?> 



second side plates holds good in the specimen I have 

 specially examined, but these teeth are so small in L. brevi- 

 cornis that their absence is not a very important character. 

 The third pleon segment has the lateral margin straight 

 and shows no emargination above the postero-lateral tooth; 

 the slender finger of the fifth pair of peraeopods is not 

 more than one-third the length of the propod. and is thus 

 similar to the figure given by Sars : the length of this finger 

 appears to vary, being longer in smaller specimens ; the 

 telson has only a single seta in the notch at the end of each 

 lobe, thus agreeing with Sars' figure and differing from 

 Stebbing 's description. The slight differences mentioned 

 by Stebbing in the gnathopods appear of little importance, 

 those of my specimen agreeing quite closely with the figures 

 given by Sars, the palm of the second having a small con- 

 cave depression near the base of the finger. 



L. brevicornis Bruz. is known from the Arctic Ocean and 

 the North Atlantic. If L. aeqitabilis is really the same its 

 range is extended to Australian seas. 



The species L. proximo, Chevreux from the Gambier 

 Archipelago should, in Mr. Barnard's opinion, become a 

 synonym of L. aeqnabilis. He records it from False Bay, 

 South Africa.

Locality. Tasmanian Coast. Two specimens, the largest 

 15 mm. long. (Reg. No. E. 5352.) 



These specimens agree on the whole with the description 

 of this species given by Stebbing in 1906. The sixth and 

 seventh segments of the peraeon are produced into a sharp 

 dorsal tooth and there is a minute tooth on the fifth seg- 

 ment also ; the teeth and carinations on the pleon are as 

 described by Stebbing. 



L. dubia is known from Australia, New Zealand, South 

 Africa, the South Orkneys, and South Victoria Land. The 

 closely allied species L. consanguinea has been recorded by 

 Stebbing from Kerguelen and Heard Islands and by Chev- 

 reux from Marguerite Bay in the Antarctic. The two 

 species present many points in common which are also 

 found in the European species L. /is.vicoriiix (Sars.)
