1901.] MOLLUSKS FEOM THE PEESIAN GULP. 431 



Telegraph Co. at 45 fathoms. Described (Ann. Nat. Hist. ser. 7, 

 vol. iv. p. 462) as of the subgenus Cylinder, but though the 

 markings are almost identical with those of C. episcopus, the 

 carinated spire undoubtedly comes near to G. acuminatus Brug. 

 and other Leptoconi. It is among the most beautiful of Cones and 

 the finest mollusk yet found in this region, being in form like C. 

 gloria -maris, but with OA-en more conspicuous spire. Commander 

 E. li. Sbopland has shown us a specimen in juvenile condition 

 from the vicinity of Aden. Two examples, averaging 5 inches in 

 length, were procured by Mr. Townsend ; a third, said to have 

 been fully 7 inches long, unfortunately was missed. 



CoNirs (Leptoconus) dictatoe Melv. 



P.G. Shaikh Sliuaib Island, at 10 fathoms, in coral-sand. 



CoNUS (Leptoconus) ELEGAisrs Sowb. 



P.Gr. Henjam Islaud. 25 fathoms, mud. Another on the 

 telegraph-cable in the Gulf of Oman, beautifully variegated with 

 fulvous markings, but more frequently found dead and discoloured. 



M.C. Charbar Bay, 7 fathoms, mud ; and Ormara Bay. 



CoNUs (Leptoconus) iisrscuiiPTTJs Kien. 

 I. Bombay (^Ahercrombie). 



CoKus (Leptocokus) lentiginosus live. 



I. Common at Bombay (Ahercrombie). Endemic in the North 

 Arabian Sea. Bombay Harbour, southwards {Lf.-Col. II. D. Olivier). 



CoNus (Leptoconus) longukiojvis Kien. 



P.G. Malcolm Inlet or Kubbatt Ghazira, near Maskat. Muddy 

 sand, at 24 fathoms. All so-called C. acideiformis Eeeve from this 

 region seem invariably to be the allied and little understood 

 longurionis of Kiener. 



CoNUs (Leptocotstus) milesi Sm. 

 P.G. Maskat, 5-20 fathoms. 



Coitus (Leptocokus) oebignti Aud. 



P.G. and M.C. (Borders of). A few juvenile examples at 

 20 fathoms S.E. of .Task. 



CoNUS (Leptoconus) planilieatus Sowb. 



Conus (Leptocomts) planiliraius Sowb. Proc. Zool. Soc. 1870, 

 p. 255, pi. xxii. fig. 1. 



P.G. Shaikh Shuaib I. A single specimeii in fine condition 

 at 7 fathoms. 



I. With C. clytospira M. & S. and acutangulus Chemn. on 

 telegraph-cable at 45 fathoms, 125 miles W.S.W. of Bombay. 

 Very abundant, but all dead and found adhering to the pitch of 

 the cable : perhaps one hundred or more examples. For remarks 

 on this species consult E. A. Smith (Ann. Nat. Hist. ser. 6, 

 vol. xiv. p. 159).
