are, however, larger and narrower and much more fiiiely and closely 

 sculptured than the normal form. They do not seem to belong to 

 T. araneosus, Philippi, which is quoted by Caramagna from Aden. 

 T. gratus, Desh., and T. quadriradiatus, Desh., should, I think, be 

 regarded as varieties of T. obscurata. 



203. Tapes virgineus, Linn. 



Hab. "In Indiis" (Lihw.); New Holland (Romer) ; China Sea 

 (Philippi). 



Ron er's figure 3 rf on plate xxxiii. of his monograph of Tapes 

 represents the form of the specimen from Aden, but the colouring 

 is not quite the same. 



204. Venerxjpis macrophylla, Deshayes. 

 Hab. Philippine Islands ; Aden (Jousseaume). 



A few specimens from Aden apparently belong to this species, 

 which A. H. Cooke unites (and probably correctly) with F. irus, 

 Linn. This may be the same species as that quoted by Caramagna ' 

 from Assab, at the southern end of the Red Sea, under the name 

 Fenerupis cordieri, Desh., originally described from Californian 

 specimens. 



205. PsAMMOTvEA OBLONGA, Dcshaycs. 

 Psainmotella oblonga. Reeve, Con. Icon. f. 7. 

 Hab. ? 



The finest example from Aden is considerably larger and of thicker 

 substance than the shell figured by Reeve. It is 83 millim. long 

 and 4 1 high. The valves towards the umbones are purplish, the 

 rest of the surface being dirty whitish. The purple tint behind the 

 apices is much darker than in front. 



206. PsAMMOBiA (Heteroglypta) corrugata, Deshayes. 

 Hab. Zebu, Philippines. 



207. Psammobia pallida, Deshayes. 



P. pallida, Desh. Proc. Zool. Soc. 1854, p. 323. 

 Hab. Red Sea ; Malacca (malaccana and suffusa). 

 P. malaccana. Reeve, is a synonym of this species, and P. suffusa, 

 Reeve, a variety. 



208. AsAPHis DEFLORATA (Linn.). 



Hab. Red Sea, Indian and Pacific Oceans ; also West Indies ; 

 Aden {Caramagna). 



209. Tellina (Tellinella) sulcata. Wood. 

 Hab. Philippine Islands, Red Sea; Aden {Cooke). 



The figures in Romer's monograph of Tellina (Conch. -Cab. pi, 13. 

 ff. 4, 5, 6) give a good idea of the Aden specimens. This species 

 in Cuming's collection bears the name of T. woodii, Deshayes, 

 but I do not think that this has been published.
