1S75.] G. & H. Nevill — Descriptions of new Marine Mollusca. 103 



part of the new marine species described from New Caledonia by M. 

 Crosse and Souverbie ; for instance, we had prepared a description of a 

 new JEuchelus found by one of us alive at extreme low water on a reef at 

 Port Blair, Andaman Islands ; on receipt, however, of No. 1 of the 

 Journ. de Conch, for 1875, we found the same species admirably described 

 and figured by M. Souverbie fromN. Caledonia, under the name of Troclms 

 (Euclielus) fossulatulus. 



Teochus Satrapius, v. Mart. 



Nov. Conchol. Sup. V, {Bushire). 

 T. (Clanculus) Tonnerrei, Nevill, J. A. S. B., 1874, {Aden). 



The specimen described by v. Martens is considerably bigger than any 

 found by us at Aden ; in other respects they seem to be exactly similar ; the 

 denticulations at the base of the columella and within the outer lip were 

 not sufficiently marked in our figure, though properly recorded in the 

 description. When we published our species the part of the Nov. Concho 

 containing the above description had not reached Calcutta. 



Tbochtts (Gibbtjla) Holdswoethaka, Nevill, var. 



J. A. S. B., 1871, {Ceylon). 



Minolia variabilis, H. Ad., P. Z. S., 1873, {Persia). 



This small variety was dredged tolerably abundantly in tho Gulf of 

 Oman by Mr. Blanford. After a close and careful examination we can detect 

 no difference from the type form, except in the considerably smaller size of 

 the Persian Gulf shell ; we must, however, state that in this respect we 

 have seen no intermediate specimens. The Museum possesses typical speci- 

 mens of G. Holdswortliana from Penang, as well as from Ceylon. 



In a collection of shells, numbering some 600 or 700 species, dredged 

 by Mr. W. T. Blanford off the coast of Persia, and presented by him to the 

 Indian Museum, are specimens of the following interesting shells : a 

 single specimen of a species of our genus Robinsonia, perhaps our H. 

 Ceylonica ; a new species of JViso and our If. pyramidelloides (the latter 

 was also dredged in the Paumben Straits by Dr. Armstrong) ; JRissoina 

 Stoppanii and S. Bellardii of Issel, with ten other species of the genus ; 

 Fossarus Stoliczfcamcs, nobis, and three new species of the genus ; JRimula 

 propinqim, A. Ad. ; a new species of Limaea, very close to the European 

 species ; JEueharis angulata, H. Ad. and Neaera pulchella, H. Ad., &c. 



It may perhaps be well to record here that specimens of Macroclilamys 

 Geqffreyi, H. Ad. (P. Z. S., 1868, p. 290) are marked in the collection of
