PLEUROTOMA. 169 



rubbing. P. leucotropis, Adams and Reeve (fig. 37), has no dis- 

 tinctive characters except its different distribution, and may also 

 be united with this species. Sowerby reports it from Mauritius, 

 and its occurrence in tho China Sea is well-established ; on the 

 other hand the west coast of America localities of P. oxytropis 

 need confirmation. 



P. FASCIALIS, Lamarck. PI. 4, fig. 40, 45. 



Shell concavely shouldered, forming a somewhat baby Ionic 

 spire, sharply ridged throughout, the two ridges forming the 

 shoulder more prominent; yellowish to brownish, the ridges 

 dark chestnut. L. 50, diam. 18 mill. 



Philippines; Red Sea (Issel). 



P. brevicaudata, Reeve (fig. 45), appears to me to be a juvenile 

 of this species. 



P. P^ETELIANA, Weinkauff. PL 13, fig. 58. 



Whorls ten, slightly excavated above, girdled by prominent 

 lira? ; light violet brown, bilineated with white ; aperture purple- 

 brown. Length, 30 mill. 



Habitat unknown. 

 P. LIRATA, Pease. 



Shell fusiform, turreted, keeled all over, keels nearly of the 

 same size, and almost equidistant, the keel on the middle of the 

 whorls slightly the largest, the intermediate superfices concave, 

 interstices between the keels finely striate longitudinally ; sinus 

 deep ; canal short ; white, keels spotted with reddish brown. 



L. 35, diam. 12 mill. Isl. Oahu. 



Is possibly identical with P. Pseteliana, but differs in having 

 the keels spotted. I have not seen it, and no figure has been 

 published. The specific name is preoccupied. 



B. With short canal. 

 P. VIOLACEA, Hinds. PL 4, fig. 42 ; PL 3, figs. 29, 29 a. 



Shell multicarinate, the interstices longitudinally striate ; pale 

 violaceous or whitish, sometimes indistinctly fasciated with a 

 darker color above ; columella one- or two-plaited ; outer lip 

 acute, crenulated, with a slight sinus. L. 24, diam. 7 mill.

New Guinea, New Zealand, Australia.
