DESCRIPTIONS OF NEW SPECIES OF FLEUROTOMA, MITRA, 

 AND LATIRUS. 



By James Cosmo Melvill, M.A., F.L.S., etc. 



Read December lith, 1894. 



PLATE XIV. 



1. Pletjkotoma (Drii,lia) Jousseatimei, n.sp. PI. XIV. Fig. 10. 

 P. testa attenuato-pyramidali, cinereo albescente, unicolore, spira 



elongata, anfractibus octo, vcntricosis, ad suturas impressis, trans- 

 versim spiraliter striatis, longitudinaliter paucicostatis, costis obliquis, 

 nodulosis, apertura ovata, labro exteriore crassiusculo. Long. 16, 

 lat. 5'50 mm. 



Hah. — Aden (Captain E. E,. Shopland). 



Near P. incerta (Smith) and P. Cecchi (Jousseaume), the latter 

 from the same locality, but very different in texture. There is no 

 shell an exact counterpart of this amongst the vast stores of the 

 Natural History Museum, S. Kensington, nor does M. Jousseaume, 

 to whom it has been submitted, know it. I venture to associate with 

 this shell the name of that author, who has especially made the fauna 

 of Aden and its neighbourhood the subject of profound study, and 

 has added many new species to those already known. 



Of the Mitrse next to be described, three come from Aden, where 

 they were dredged by Commander E. R. Shopland, R.I.M., well 

 known as a very successful collector of Eastern Mollusca ; one, a 

 handsome Turricula, from West Australia ; and two, both originally in 

 Sir David Barclay's collection — of these, one is from the Mauritius, 

 the other of uncertain locality. 



2. MiTEA (Pusia) EvELYNiE, n.sp. PI. XIV. Fig. 1. 



M. testa oblongo-fusiformi, elongata, ochracea, solida, apice sub- 

 acute, anfractibus novem, apud suturas impressis, gradatulis, undique 

 dense cancellatis, cancillis • regulaiibus, nitidis, liammis fulvis late 

 maculatis, apertura oblonga, auriculata, columella quadrij)licata. 

 Long. 32, lat. 12 mm. 



Hab. — Mauritius [oUm in coll. Barclay). 



Allied, to some extent, both in texture and disposition of colouration, 

 to M. Adamsonii (Gray), with which it has been hitherto confounded. 

 From this it differs entirely in form, that species being short, obese, 

 and with much ventricosity of the lowest whorl, and presenting more 

 of the appearance of M. cucumerina (Lam.), the cancellation and 

 ribbing being also much finer and more frequent in M. Adamsonii, 

 and the shell not so shining, and much smaller. The fonn of the 

 mouth is much the same. There were, I believe, two specimens of 

 this handsome shell in the collection of the late Sir David Barclay, 

 dispersed in 1891.
