154 " ENDEAVOUR " SCIENTIFIC RESULTS. 



I have duplicates of specimens which I had sent to Ehlers 

 from Waiheke, near Auckland, New Zealand, and noticing 

 the resemblance between the Victorian specimen and Ehlers' 

 account, I examined the New Zealand species. I find that 

 the second or smaller sort of dorsal chsetse are totally unlike 

 those figured by him for the A. amyliiglypta from South 

 Georgia, Avhere he describes them as acicular in form. In the 

 Waiheke specimens, however, they are transparent bristles, 

 with a Avide flange which is not traversed by the shaft and 

 has the striations palmately arranged, instead of pinnately — 

 that is, they radiate from the end of the shaft. These chsetse 

 are situated anteriorly to the longer capillaries, not pos- 

 teriorly as the acicular-like chseta? in A. amphiglypta are 

 stated to be. 



It is possible that Ehlers overlooked these smaller chsetse, 

 which only just project through the skin. When mounted in 

 Canada balsam the flange is scarcely visible, and then they 

 appear bluntly pointed ; again, the capillaries, which he 

 represents as " jointed," are, in the New Zealand as well as 

 in the Victorian species, finely biserrulate along the fine 

 apical point. 



The present Morm is quite distinct from the New Zealand 

 species and from A. amphiglypta. I have placed it in 

 Kinberg's genus Asychis, since it appears to agree better 

 with that than with any of Malmgren's genera, but as I have 

 but Httle recent literature on the family, I have described 

 the external features somewhat in detail.
