1 6 Melvill, Molluscan Fauna of the Arabian Sea, etc. 



We carefully compared the shell with the description 

 and figure of M. deformis Nevill, from Ceylon, the marking 

 being similar, but form entirely different. 



With a few other interesting Mollusca, this was 

 dredged by Captain Tindall, during a cruise of the 

 S.S. " Patrick Stewart," in 1896, off the Malabar Coast and 

 West of Ceylon. We may add that some of the specimens 

 were encrusted with a coral {Heteropsammia sp.*) 



Marginella (Persicula) OODES, Sp. nov. 



(PI. I, f 16.) 



M. testa minuta, crassiuscula, perlcevi, albida, nitida, 

 spzra omninS immersa, anfractu ultimo globoso, apertura 

 oblonga, angusta, labro percrasso, nitido, IcEvi, intus planato, 

 non denticulato, colu7nella quadriplicata. 



Long. 2, lat. I "25 mm. {sp. maj.). 



Hab. Bushire (Persian Gulf). 



About a dozen examples of a little pure-white shining 

 Cyprcea-X-^^ shell, globose, with spire wholly immersed, 

 the mouth narrow, oblong, the outer lip very thickened, 

 quite smooth and not denticulate within. Columella four- 

 plaited. From Issel's description of his M. pygmcea, which 

 must be near this species, the colour is yellowish, and the 

 outer lip is denticulate within. From the figure we would 

 gather the mouth was narrower than in our species, 

 and the form more oblong than globose. Issel described 

 it from one example only, found in the Gulf of Suez, and 

 what purports to be it has also been once recorded from the 

 Persian Gulf It is very likely this nearly allied species.

FUSUS ARABICUS, Sp. nov. 

 (PI. I, f 6.) 

 F. testa parva, attenuata, lanceolata, gracilis anfrac- 

 tibus novefn, duobus apicalibus brunneis ofnninS Icevibus^
