natural distribution of this numerous and heterogeneous genus, will 
retain the appellation of Rhynchites , pr. diet., regardless of the 
variations of length of the rostrum, too secondary a character—com¬ 
pared with their numerous affinities—for their separation, as Schonherr 
artificially did it.

This species has a peculiar construction of the head and rostrum 
taken together, compared with the other species of Rhynchites. The 
head is rather elongate, subconically angustate from the base to the ros¬ 
trum, as in Rhynch. rugosus , and much like the other species of the group 
of Auratus (or spinose $); but the rostrum, instead of being narrower 
than the head, is almost even with the anterior part of that organ 
in width and thickness, seeming to be its mere continuation, and 
the eyes being very flat much increase that appearance. The rostrum 
is subangular at the sides, flat above, with a basal carina, more or less 
distinct. The forehead is impressed, and, like the rostrum and the
