230. Blanfordia striatula. Menke. Plate XV. Fig. 13 natural 



size, 13 a., 13 b. much enlarged, 13 c. operculum of same. M.C. 



Menke, Moll. Nov. Holland, p. 9. 



Shell rimate, truncately fusiform, rather smooth, not shining-, covered 

 with dull olivaceous epidermis ; spire tapering, decollated, suture 

 distinct ; whorls in adult state 4, gradually increasing ; aperture 

 almost vertical, its axis slightly oblique, elliptical ; peristome rbd- 

 dish-brown within, moderately thickened, and on columellar margin 

 expanded, leaving uncovered a small umbilical fissure ; operculum 

 black, horny, 3 4 spiral. 



Length 0-33 ; breadth 0-17 ; aperture 0-07 long, of an inch. 



Habitat. Adelaide, South Australia. Tasmania. Angas. Botanic 

 Gardens, Melbourne, Victoria. Brazier. 



I cannot find any clue whatever to the work in which this genus was 

 first published by Menke ; in fact my only record of it is a remark 

 by Angas, in Pro. Zool. Soc, 1863, p. 523 ; and the characters above 

 are taken from specimens in my collection. Pfeiffer, in his Supple- 

 ment II., 1865, p. 8, of Pneumonopomorum Viventium, in alluding to 

 this species, doubts to which genus it belongs. 



231. Blanfordia pyrrhostoma. Cox. Plate XV. Fig. 14, 

 14 a. Australian Museum. 



Shell rimate, cylindrically tapering, decollated, obsoletely rib-striated, 

 especially on the first whorl, and there decussated with fine spiral 

 lines, dull white without lustre ; spire very regularly tapering ; 

 whorls, at least, six, uniformly slightly convex, last convex ; aper- 

 ture slightly oblique, its axis divergent from that of the shell, nearly 

 elliptical; peristome white, inside of mouth bright red, enamelled, 

 margins slightly joined by a callus, expanded, especially below and on 

 columellar margin, leaving uncovered a minute umbilical fissure and 

 aperture. 



Length - 70 ; breadth 0*30 ; aperture 0*20 long, of an inch. 



Habitat. Sharks Bay, Western Australia. Masters. 



The only specimens of this shell (4) which I have seen are in the 

 Australian Museum. All have a dull, dead, semi-fossil chalky look, 

 yet the brightness of the enamelled mouth shews that they are not 

 " dead shells." Probably the number of whorls will be found to be 

 about 9. 



Genus 



DIPLOMMATINA. Benson. 



Shell minute, dextral or sinistral, thin, conical, whorls 

 costulated, convex, last sub-ascendant ; aperture nearly 

 circular ; peristome double, outer expanded ; operculum
