22 Mr. J. C. Melvill and Mr. Abercrombie on 



(II.) Persian Gulf. — This Fauna has been but very Httle 

 studied, and we cannot discover more than three papers 

 which have been published exclusively on the subject. 



1. Issel, in 1865, gave to the world a list of shells found 

 at Bunder-Abbas, and the Isle of Ormus, by G. Doria and 

 Philippi, but only 17 species are included.* 



2. Dr. E. von Martens in 1874 enumerated the MoUusca 

 of Bushire, as found by M. Hausknecht, amounting to 49 

 in all, and to which a treatise is devoted. — Ueber Vorder- 

 asiatische Cofichylien, Cassel, 1874. 



3. Lastly, M. F. Houssayf explored the shores near 

 Bender-Bouchir, on the East coast of the Persian Gulf, in 

 1884 — 1886, and Dr. P. Fischer has catalogued '^2) species, of 

 which the following are found also in Bombay. 



Siphonaria Kiirracheensis (Reeve). 



Purpura carinifera (Lam.). 



Cerithiuni inorus (Lam.). 



(but of the form C. clypeomorus (Jousseaume). 



Potainides fliiviatilis (P. & M.). 



Uinboniuni vestiarium (L.). 



Lucina fibula (Reeve). 

 (III.) Karachi. — We can find no very recent catalogue 

 of shells from this port, but in Dr. P. Fischer's Matmal de 

 Conchy liologie, p. 160, a list is given, as having been formed 

 by the late Col. Baker. Unfortunately, many are only 

 generically, not specifically, alluded to, which renders 

 identification not possible. We are, however, able to point 

 to ten species common to both places, and this number will 

 probably some day be very largely increased. 



(IV.) Ceylon. — The lists of the Molluscan Fauna of 

 Ceylon that we have compared with our Bombay catalogue 

 are chiefly those of Sir J. Emerson Tennant (Ceylon, Vol. I., 



* Catalogo dei Molluschi raccolti dalla Missione Italiana in Persia {Memoire 

 della Reale Accademia delle Scienze di Torino, serie II., vol. 23, 1865).
