Specimens of each species in which the anterior angles of the head are not pro- 

 minent appear to be without exception of comparatively uniform size. With the 

 exception of A. tricornis, whose head is markedly peculiar, and .-1. laniger, which 

 seems to be very rare, this is the only one of these species yet described which is 

 large enough to be identified with the biggest of the specimens to which Kaup applied 

 the name emarginatus. His other .specimens must have belonged to different smaller 

 species, including perhaps .-1 . alutaceosternus.
