Fam. Yeemetid.e. 

 Yeemetes sp. 



1. Bombay (Abercrombie). round cast up from deep-water 

 amongst shell-sand. 



SlEIQEARIA sp. JUV. 



I. Lat. 18° 58' IS'., long. 71° 45' E. ; 40 fathoms. 



Fam. Strohbed^e. 

 Strombus (Gaelenela) defoemis Gray. 



M.C. A single dead specimen only dredged, without more exact 

 record of locality. 



Steombes (Gallinela) eesieormis Sowb. 



P.G. Shaikh Shuaib Island, &c. This rare species, queried by 

 Tryon (Man. de Conch, vii. p. 117) as inhabiting the Red Sea, 

 seems to be general in the Persian Gulf, being found at from 

 7 to 10 fathoms in coral-sand bottom. Many varieties occur, one 

 being pale lemon-yellow. Juvenile examples exhibit strong varices 

 and transverse striation throughout. In the Gulf of Oman it 

 occurs near Maskat at 15 fathoms. 



Steombes (Cakabium) floredes Lam. 



M.C. Charbar. On mud-covered rocks at low tide. 



Steombes (Canaeiem) gibbeeulus L. 



P.G. Maskat, 15 fathoms. Not common in the Gulf, but 

 one of the most widely-distributed gastropods in the Indo- 

 Pacific region. 



I. Bombay {Abercrombie). Bassein, southwards (Lt.-Col. II. 

 D. Olivier). 



Steombes (Canariem) yeebueyi E. 8m. 



P.G. Kais and Shaikh Shuaib Islands. From 7 to 10 fathoms, 

 coral-sand. Our examples appear almost intermediate between 

 typical yerburyi and pidchellus Eve., and suggest these two being 

 extremes of a variable species. 



Steombe's (Coxomeeex) belechiexsis l Melv. (nom. emend.). 

 (Plate XXL figs. 13, 15.) 



P.G. Linjah. 31 fathoms, December 1900. Maskat {Dr. A. R. 

 Jayalcar). 



M.C. Charbar. 7 fathoms, mud and sand. 



The more recently-dredged Persian Gulf examples exhibit variety 

 in colour and marking, though none in form. One example is 

 banded with pale straw-coloured fascise, the spaces filled with 

 delicate zigzag lines ; another strongly banded with dark-brown 

 fasciae of varying thickness. The first examples discovered in lb98 



1 I described this as helutschiensis, but venture to emend the spelling to 

 beluchiensis as more in harmony with the dictates of orthography.— J. C. M.
