1901.] MOLLUSKS FROM THE PERSIAN GULF. 433 



CoNus (Ehizoconus) traversianus E. a. Smith. 

 P.Gr. and M.C. JSTo exact locality given. At from 20 -33 f ms. 

 on cable and in mud and rocky ground. 



Also received from the Andaman Islands (Booley). 



CoNUS (Cheltcontts) achatinus Chemn. 



P.Gr. Gulf of Oman, Jask. Just on the borders of M.C. also 

 at Charbar on mud-covered rocks at low tide. This appears to be 

 the 0. nigropunctatiis Sowb. 



I. Bassein, Bombav Harbour, and southwards to Goa {Lt.-Col. 

 E. D. Olivier). 



CoNus (Cheltconus) monachtjs L. 



I. Bombay (Abercrombie). Nearly allied to the preceding. 



CoNUs (Cheltconus) piper atus Eeeve. 



I. Bombay {Abercrombie). Perhaps, as suggested by Tryon, 

 only a form of G. erythrceensis Beck. This is not absent from the 

 Persian Gulf, but we have no exact records from Mr. Townsend. 



CoNUS (Cylinder) elts^ Kien. 



P.G. Exact record not given. One characteristic example 

 of this very rare Cone. 



ConijS (Ctlindeb) omaria Hwass. 

 P.G. Tumb Island. 



CoNUS (Cylinder) pennaoetjs Born. 



P.G. Elphinstone Inlet, in shoal water on coral-sand. One 

 example exhibits a rare variation in the close interwoven 

 longitudinal zigzag chestnut lines, merging into black, on a pale 

 ground. 



CoNUS (Cylinder) textile L. 



P.G. Gulf of Oman, Maskat. Found from low-water mark to 

 20 fathoms on muddy rocks. 



Yar. verriculum Eeeve (sp.). 

 P.G. Maskat. Pine. 



CoNus (Hermes) thomasii Sowb. 



M.C. Charbar. A single example on muddy rocks. Perhaps 

 too nearly allied to C. terebra Born, but with less acuminate spire 

 and mouth beautifully suffused with violet. 



Plefrotoma acuti&emmata Sm. 



I. Lat. 18° 58' N., long. 7V 45' E,, 40 fathoms. 



The locality hitherto unknown. In our opinion distinct 

 from P. jubata Hinds, with which Tryon (Man. Conch, vi. p. 171) 

 associates it. 



Pleurotoma albata E. a. Sm. 

 P.G. Linjah anchorage. 7-15 fathoms, mud, rare.
