PLATE XIII. 



Eaely in 1896, througli the kind instinimentality of Mr. F. W. 

 Townscnd, of Manora, Karachi, we received from Mr. G. H. Booley, 

 of Port Blair, two small Andamanese collections, the marine portion 

 mostly having been dredged by himseK, although no data or particulars 

 of exact locality have come with the specimens. There were likewise 

 a few Helices, MelanicB, and other terrestrial or fluviatile species, 

 which, however, are not enumerated in the present paper. 



The Andaman Islands have been fi'equently searched for Mollusca, 

 and the leading and more conspicuous species would seem now pretty 

 well known to Malacologists ; few attempts, however, at cataloguing the 

 molluscan fauna have been made. Many new fonns have been of late 

 years described from this region by Mr. G. B. Sowerby, Messrs. Geoffrey 

 and Henry Nevill, and others, whilst, among the smaller species, 

 the Marquis de Folin has enumerated many novelties. 



The most important contribution of recent years has, perhaps, been 

 that of Mr. E. A. Smith, ^ in which seventy-five species, collected 

 by Lieut. -Col. L. "Worthington Wilmer, are catalogued, six of them 

 being described as new. About twenty-five of these are here recorded 

 as being in Mr. Booley's collection, including three of the six new 

 species described by Mr. Smith, viz. : Pleurotoma Wilmeri, Ficsus 

 ahiornits, and Turritella infraconstricta. 



We hope to receive further consignments fi*om Mr. Booley, and, 

 in time, to be able to off(!r lists of productions of these prolific 

 Islands to the members of the Malacological Society ; in the meantime, 

 we would mention that our catalogue contains over ninety species, 

 six being considered new. 



The species already recorded in Mr. Smith's paper are distinguished 

 by an asterisk. 



1. Hydatina (Aplttsteum) aplustke, L. (= Amplustre ThalassiarcJii, 

 Mart.). Extends to Mauritius. One juvenile example. 



2. * Atys cylindkica, Helbling. A large example. 



3. ToKNATINA cf. OLIVULA, A. Ad. 



4. Teeebea cinerea. Born. According to Tryon, a variable 

 species, of which the name cinerea should be taken as the aggregate.
