1901.] MOLLUSKS FROM THE PEHSIAK GULF. 389 



possesses kinship, especially, with E. solicla Sowb. and inflexa 

 Pease, from both o£ which it can be differentiated by its delicate 

 translucent substance and smaller size. From E. australasiaca 

 M. & S., recently described from the Torres Straits, it differs in 

 greater attenuation and rapidly contracting spire. It much 

 exceeds in size E. latijpes Wats., and is broader in convolution of 

 body-whorl than any varieties of E. gentilomiana Issel and 

 E. shoplandi Melv., both of which occur in the same seas. The 

 specific term chosen indicates its Stylifer-like appearance.

1 Niso pyramidelloides G-. & H. Nevill (Journ. As. Soc. Beng, vol. xl. pt. ii. 

 p. 5, pi. i. fig. 14, 1871), is undoubtedly near this species, but considerably 

 smaller. It is reported from the "Persian Coast" by Nevill {t. c. vol. xliv. 

 pt. ii. p. 103) as having been collected by Mr. W. T. Blanford.
