on the penultimate and last whoiis these ribs become more promi- 

 nent at the angle of the whorl and on the spiral ridge in front of the 

 suture. On the last whorl the ribs may be continued for a short 

 distance in front of the angle but are less prominent, and bend 

 towards the aperture. Between the ribs fine growth-lines occur. 



Aperture rather long, becoming somewhat narrower in front. 

 Anterior canal rather long, with thick walls, nearly straight, but 

 with the extremity bent inwai-ds to form a small, pointed projection. 

 Outer lip thick, wing-like, with a stout lobe projecting beyond the 

 level of the last suture, and with a deep posterior notch separating 

 the lobe from the rest of the lip. Externally the lobe is channelled, 

 and in front of it there is a sinuosity. Inner lip forms a large, 

 thick, rounded mass of callus, which extends across the whorls 

 nearly to the apex of the spire. 



Length 41 mm. ; breadth 23 mm. 



Affinities. — Pugncllus auriculatus appears to be readily distin- 

 guishable from the other known species by the character of its 

 ornamentation. The genus is widely distributed and is especially 

 characteristic of the Chalk of the Indo-Pacific region, having been 

 found in the Libyan Desert, Madagascar, Baluchistan, Southern 

 India, Borneo, New Zealand, Colorado, California, Texas, Utah, 

 Wyoming, Quinquina (Chili), and Southern Patagonia. Cossmann '-^^ 

 states that Stromhits crassilabrum, Zittel, from the Gosau Beds, 

 probably belongs to this genus. In Pondicherri Pugnellus is found 

 in the Valudayur and Trigonoarca Beds, and in Trichinopoli in the 

 Trichinopoli and Ariyalur Groups.

 Forbes). 

 An imperfect specimen was identified by Griesbach with P. 

 uncatus (Forbes),! but it differs from that species in several 

 respects : the shell is more elongate, the spiral angle smaller, the 

 whorls of the spire more flattened, the posterior part of the last 

 whorl is concave, transverse ribs occur on the penultimate as well as 

 on the last whoi'l, and spiral ribs appear to be absent. The trans- 

 verse ribs become broader and more prominent where they cross the 

 angle of the last whorl.
