PLATE III. 



SiN^CE our first paper on the subject/ in which ninety-seven species, 

 forwarded by Mr. G. H. Booley, of Port Blair, were enumerated, we 

 have received several consignments from the same careful and enter- 

 prising collector, mostly containing sj)ecimens differing specifically 

 from those in the earlier parcels : these we now proceed to enumerate. 

 Mr. Booley has been directing his attention to particular genera, and 

 it will be seen that Oliva, Terebra, and Nassa predominate in the 

 present paper. 



We put forward these lists on the supposition that any additions 

 to the meagre details hitherto published of the exceptionally rich 

 molluscan fauna of the Andaman Islands must prove of unusual 

 interest, seeing that those islands are situated in the centre of the 

 Bay of Bengal, and cannot fail to present an almost exhaustless field 

 for research. This list inckides 215 species, and of these, two species 

 of Terebra, as well as marked varieties of T. crenulata and T. nitida, 

 are considered new to science. We should add that a few of the 

 species did not come from Mr. Booley, but were collected some years 

 ago by Mr. J. E. Henderson, of Madras, and are now in the Manchester 

 Museum, Owens College. We thought it a good opportunity to 

 include these also in the present communication, in order that the 

 records might be made as complete as possible, although the attain- 

 ment of this desired end can only be reached by degrees. 



We have further taken this opportunity of figuring the operculum 

 of Ancilla Booletji, Melv. & Sykes ^ (PI. Ill, Fig. 7). 



Having received additional specimens of Turritella leptomita, 

 Melv. & Sykes, ^ we think it right to call attention to the possibility 

 of its eventually proving a variety of the Eglisia tricarmata, 

 Adams & Eeeve, described and figured in the Yoyage of the 

 "Samarang," and refigured here (PL III, Fig. 6) for comparison. 

 While differing from the large and, presumably, type specimen in 

 the British Museum (N'atural History), closer afiinity appears on 

 comparison with two smaller specimens mounted on the same tablet. 

 The " type " has five caringe at least on the last whorl, and
