2 Melvill, Molluscan Fauna of the Arabian Sea^ etc. 



{D. resplendens) unique for fine polish and brilliant 

 colouring, two Bullies, one {B. ceroplasta) peculiar and 

 unusual in form, a pretty Scalaria (5. malcolmensis) from 

 Malcolm Inlet, on the S. of the Persian Gulf, and Fusus 

 arabicus, a dwarf species of typical form and character, 

 from Muscat, where also occurred the striking Mytilicardia 

 FJinchi, which, at the request of Mr. Townsend, we have 

 named after Mr. B. T. Ffinch, CLE., chief of the staff of 

 the Indo-Oceanic Telegraph Service. Two more examples, 

 also, of the beautiful Scalaria finibriolata Melv., having 

 occurred off Muscat, the largest (a remarkably perfect 

 example measuring 52 mm. in length, and well preserving 

 the salient characters of the original description, by which 

 it was differentiated from 5. decussata Kien) is here figured 

 (PI. I, f 12). But, of all the forms, a new Strombus is 

 perhaps the most unlooked for. It is now very many 

 years since any additions were made to this genus, and 

 monographers have considered it complete. The species, 

 therefore, for which I propose the name belutschiensis, 

 dredged off Charbar, on the coast of Beluchistan, is there- 

 fore exceedingly noteworthy. It only came to hand during 

 the preparation of the present paper, and may be regarded 

 as the first fruits of Mr. Townsend's fresh dredging expe- 

 dition (1898). 



I have also included in the present paper certain new 

 species dredged by Captain Tindall, of the S.S. " Patrick 

 Stewart," either on the Angrias Bank, W. of Bombay, 

 at Quilon, on the Malabar Coast, or near Batticaloa and 

 Hambangtotte, E. and S. Ceylon respectively. From the 

 two former, especially, came some good results, e.g., 

 Ancilla Tindalli, a distinct addition to a circumscribed 

 genus, Marginella quilonica, an elegantly banded shell, 

 and Calliostoma duricastellum, this last dredged abun- 

 dantly at Batticaloa. One example of the true Scalaria 

 decussata Kien, was also dredged off the Angrias Bank.
