XX VI.—Descriptions of Sixty-eight new Gastropoda from the 
Persian Gulf, Gulf of Oman,and North Arabian Sea, dredged 
by Mr. F. W. Townsend, of the Indo-European Telegraph

Manchester Museum. 
[Plates XX.-XXIII.] 
Two years ago we published a Catalogue * of the Mollusca 
of the Persian Gulf, &c. (Cephalopoda, Gastropoda, and 
Scaphopoda only), mainly collected by Mr. ‘Townsend in 
1893-1900, and enumerating 935 species. In the interim 
further large consignments have been frequently forwarded 
by the same energetic collector from many different stations 
and depths, including especially the results of one particu- 
larly profitable dredging on 7th April, 1903, in the Gulf of 
Oman, lat. 24° 58’ N., long. 56° 54’ H., at 156 fathoms, which, 
it is no exaggeration to say, positively teems with novelties. 
All this has naturally delayed publication of the second 
portion—to contain the Pelecypoda—of the above-mentioned 
Catalogue. 
At the present opportunity we offer descriptions of many 
Gastropoda, mostly of small size, though a tew—e. g., Murex 
* Proc. Zool. Soc. 1901, vol. ii. pp. 827-460.
