On neio CoJeoptera from New Zealand. 405 



Other specimens in the collection present the same features. 

 A second species in M. Mouhot's collection, also from Siani, 

 seems identical with A. Mouhoti, but is not sufficiently well 

 preserved. The same is to be said of a specimen from 

 Australia, collected by J. B. Jukes, Esq. A larger specimen 

 (foot 10x5 centim.) presents the same specific features, but 

 is devoid of colour (bleached?). 



The question of the systematic position of this group is of 

 interest, as it seems to form a connecting-link between the 

 Cephalaspidea and Anaspidea in the following particulars : — 

 (1) Ilhinophora (cf. Acera) in close proximity to anterior 

 end of pleuropodia, in contrast to the position in, e. g., 

 A. limacina. (2) Visceral mass posterior (with shell and 

 mantle) and not yet entirely fused with foot {vide fig. 5). 

 These characteristics mark it off sharply from the genus 

 Syphonota, which Adams has proposed (on very insufficient 

 grounds). If this genus is to be retained, these points must 

 be taken into consideration. 



Besides these forms there are in the collection other 

 unexamined and probably new forms of the Aplysiidse. 

 There are, moreover, many representatives of the genera 

 Dolahrifera^ &c.j forming good material for further work, 

 though unfortunately with " spirit "-specimens.
