BOTIIRIEMBRYON. 9 



Fig. 30 is a small specimen from Cape Naturalist. There are 5 

 whorls, the last inflated below, almost imperforate. It is beautifully 

 streaked with opaque, glossy white on a corneous and purplish-brown 

 ground. Alt. 20, diam. 11, longest axis of aperture 10.7 mill. The 

 aperture is decidedly more oblique than in the typical form from 

 King George Sound. It is not unlikely that this will prove a 

 geographic race or variety. From the Cox collection. 



Var. solidus, n. var. Fig. 28 represents a very solid, strong, 

 opaque shell, with 0^ whorls, the aperture less than half the alt. 

 The surface is dull, rough, and obscurely streaked with ochraceous 

 and purplish on a dirty white ground. It is from Western Australia, 

 exact habitat unknown. The type is in Dr. J. C. Cox's collection. 



The en! ire series is remarkable for the beautifully distinct pitting 

 of the nepionic shell, which has a fraction of a whorl more than usual 

 in the genus. The last nepionic whorl is quite high, and more or 

 less variegated on the latter part. 



B. PHYSOIDES (Reeve). PL 2, figs. 35, 36, 37. 



Shell ventricosely ovate, thin, inflated, scarcely umbilicated. 

 Whorls 5, longitudinally roughly -striated, plicately crenulated at 

 the sutures; columella reflected, lip simple, yellowish, mottled with 

 white. (Reeve.) 



Western Australia (Mus. Cuming.) 



Bulimus physoides Menke MSS., REEVE, Conch. Icon. pi. 70, f. 

 507 (July, 1849) B. physodes Menke MSS., according to Pfr. 

 Bulimus (Liparus) physoides Reeve, E. A. SMITH, Proc. Malac. Soc. 

 Lond. i, p. 95, pi. 7, f. 30 and var., f. 31, (including B. brazieri as 

 a variety). 



" This species has been considered by Pfeiffer and Cox a variety 

 of B. melo. I am inclined to think that it is sufficiently distinct for 

 specific separation. It is of thinner texture, not quite as broad and 

 robust, has a thinner white columella with a purplish brown zone 

 around the closed umbilical region. In B. melo the umbilicus is 

 slightly open, the columella more thickened, more reflexed, and of a 

 purple-brown tint, and there is no basal zone of that color. In the 

 latter character B. kingii agrees with the present species, but is more 

 elongate in form. 



" The variety brazieri is rather more coarsely granular than the 

 typical form, but agrees in other respects.
