Mr. A. S. Woodward on the Dentition of Waiwo^i^x?^. 281 



oribus, scapo apice leviter ruguloso ; elytris griseis ochraceo 

 mixtis, granulis maculisque parvis, nigris, nitidis, numerosis ; 

 apicibus truncatis, angulis productis. 

 Long. 32 mm., lat. 10 mm. 



Hah. New Guinea. 



Pubescence dull leaden grey on the head and thorax, light 

 grey on the underside of the body, somewhat darker on the 

 legs, and a light grey mixed with ochreous on the elytra. 

 Head somewhat large ; eyes large and subapproximate ; a 

 median impressed line on the face and vertex. Superior 

 lobes of the eyes margined behind on the vertex with minute 

 black dots. Antenna3 with the scape rather stout, somewhat 

 rugose towards the apex, as in species of Apriona ; first to 

 third joints and base of fourth grey, the rest sooty brown. 

 Prothorax with two transverse wrinkles in front of the 

 middle, the lateral spines scarcely directed upwards and not 

 constricted at the base. Elytra with a very small trans- 

 versely directed tooth at each shoulder, with numerous small, 

 black, scarcely raised granules near the base ; posteriorly 

 these granules arc replaced by spots which extend almost to 

 the apex. The latter transversely truncate, with the angles 

 produced into short spines, the outer spines very slightly 

 longer than the sutural. 



Much smaller and otherwise distinct from any of the species 

 of the genus hitherto described.

XXXIY. — Note on an Abnormal Specimen of the Dentition 

 of Rhinoptera. By A. Smith Woodward, F.G.S., 

 F.Z.S. 



Mr. William Davies has recently presented to the Zoolo- 

 gical Department of the British Museum a remarkably 

 abnormal example of the dentition of the Selachian genus 

 Ehinojjtera, which seems worthy of a brief notice, from the
