1901.] MOLLESKS EfiOM THE PEBSIAN GTLF. 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 C. aeuminatus Brag, 

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

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

 gloria-marts, but with even more conspicuous spire. Commander 

 E. K. Shopland 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, unfortuuately was missed. 



Coots (Leptocoes) dictator Melv. 



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



Coots (Leptoconus) elegaxs Sowb. 



P.G. Henjam Island. 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.

 Arabian Sea. Bombay Harbour, southwards (Lt.-CoLB. D. Olivier). 



CoOTfl (Lbfeocoots) longerionis Kien. 



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

 sand, at 24 fathoms. All so-called C. ac ale if or mis Reeve from this 

 region seem invariably to be the allied and little understood 

 luntjurionis of Kiener.

 P.G. Maskat, 5-20 fathoms.

 telegraph-cable si 45 Eathoms, 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 consul! E. A. Smith (Ann. Nat. Hist. ser. 6,
