MELVlLL AND STANDEN : MARINE MOLLtfSCA OF MADRAS. 8$ 



Family LUCINIDsE. 



Llicina pisum Phil. — About eight examples of a highly chased 

 and ribbed small shell, very rotund, evidently of wide distribution, as 

 it has been dredged both at Port Essington, Australia, and Singapore. 1 



Lucina (Cyclas) semperiana Issel. — A minute Lucina, with 

 some extraneous resemblance to the last (Z. pisum). Like many of 

 the genus, it is of wide distribution, being reported from Mazatlan 

 (Paetel), and Gulf of Suez (Mus. Brit.) 



Tellina (Tellinella^ deltoidalis Lm. — Some very fine examples, 

 quite typical in form. Australia, New Zealand. 



Tellina (Tellinella) rostrata L. — Few, rather poor. Philippines. 



Tellina (Tellinella) undulata Hani. — Young examples only, 

 but quite characteristic. West Columbia. 



Tellina (Arcopagia) savignyi A. Ad. — Karachi (Townsend), 

 and probably all round the Indian coasts. Red Sea (Paetel). 



Tellina (Tellinula) valtonis Hani. — Very thin and delicate, 

 white, exhibiting a wonderfully beautiful iridescence. 



Tellina (Tellinides) opalina Sow. — One specimen, agreeing 

 with figure in Conch. Icon. Moluccas. 



Family CLAVAGELLID.-E. 

 Brechites vaginifera Lm. — One, somewhat worn and broken, 

 but evidently this well known Red Sea species. 



Note on Cypraea rashleighana. — The above Cowry was described in 1887, 2 

 and in the following year was re-figured, the original description being repeated in 

 the " Survey of the Genus Cyfinea, 1888." 3 Although the habitat was queried it 

 seems probable that the type came from the neighbourhood of Hongkong. Since 

 this time three or four specimens have occurred amongst the Hadfield Mollusca from 

 Lifu ; these, however, are either too young or in a not very satisfactory state of pre- 

 servation. My object in alluding to this species at the present opportunity is to call 

 attention to a very beautiful and large example which has been for years in the 

 National Collection at South Kensington, having formed part of the Cumingian 

 stores. This was figured by Mr. Lovell Reeve 4 as a stunted form of C. iabescens L., 

 but has been overlooked by Sowerby 5 and by Mr. Raymond Roberts in the ''Mono- 

 graph of Cypraa. " 6 Rather blindly following Reeve in I888, 7 I signalised this as 

 var. a of C. tabescens under the proposed varietal name of latior. Mr. Edgar Smith 

 being disposed to allow it specific rank, labelled it in the National Collection "latior 

 Melv." Last year, however, it was closely examined by us both, in comparison 

 with the original typo of C. rashleighana, and pronounced identical. The pyriform 

 shape, different dentition, narrower aperture, small clearly defined dark-brown 

 lateral punctuation, with other characteristics, differentiate this species from its 

 allies, C. tabescens, C. lens, and C. intemipta. — James Cosmo Melvill {Read 

 before the Society, April 13th, 1898).
