32 JOURNAL OF CONCHOLOGY, VOL. 9, NO. I, JAN., 1898. 



A beautifully sculptured Rissoina, allied, of course, to R. atitoni 

 Schwag., R. spirata Sow., etc., but differing from all in the decussate 

 and strongly longitudinally ribbed sculpture of the seven upper, and in 

 the acutely carinate transverse lirse of the two last whorls. The mouth 

 is oblique, outer lip extremely thickened. There is one specimen in 

 this collection and three, precisely similar, unnamed in the British 

 Museum, also from Madras (coll. Thurston). Oavfiacnos, wonderful. 



Syrnola maderaspatana n. sp. (PI. I., fig. 4). 



■5". testa fusiformi, versus apicem multum attenuata, perlcevi ; anfrac- 

 tibus quatuordecim, apicali incluso, vitreo, pellucido, c&teris ad suturas 

 canaliculatis, pallidissime ochraceo-vinctis, apud suturas utrinque pellu- 

 cide albo-ligatis ; ultimo anfractu ad peripkeria?n sub lente ochracea 

 tinea succincto ; apertura oblonga ; labro recto, marginem apud colum- 

 ellarem paullum reflexo, uniplicato. Long. 10, /at. 2*50 vim. 



An interesting shell, which at first gave difficulty as to precise loca- 

 tion. Had no plait been present, we should have deemed it a 

 Eulimella ; it is nearer in facies to an Obeliscus than a Syrnola, but its 

 distinct columellar plait places it in the latter genus. At first we 

 compared it with Obeliscus turritus Ad., but the mouth processes are 

 altogether different. The apex is in very perfect condition, and shows 

 a translucent bulbosity. 



Turbonilla coromandelica n. sp. (PI. I., fig. 5). 



T. testa pergracili, multum attenuala, albida, pellucida, delicatula ; 

 apice heterostivpho vitreo ; anfractibus quindecim, ventricosulis, un- 

 dique longitudinaliter arete recticostatis ; interstitiis Icevibus, nitidis ; 

 apertura trapezoide ; labro extus tenni, simplice, columellarem apud 

 marginem paullum refiexo. Long. 7, lat. 1*50 mm. 



Many examples of an exceedingly graceful, attenuate, shining-white 

 Turbonilla, which does not correspond with any example in the 

 British Museum collections, nor have we seen it described or figured 

 in any monograph. It does not approach any species nearly that we 

 are cognizant of, the whorls being fifteen in number, delicate, pellucid, 

 ventricosely tumid, shining, closely longitudinally straightly ribbed, 

 the interstices being quite smooth, mouth unequally square, outer lip 

 thin, simple, and slightly reflexed at the columellar margin. 



Cadulus anguidens n. sp. (PI. I., fig. 6). 



C. testa paullum arcuata, apud apicem attenuata, pellucidc albida ; 

 apertura rotimdo-ovata, margine obliquo ; apertura posteriore parvo, 

 rotundo, shnplici, teuui. Long. 8, diam. oris 1, apicalis 0*50 mm. 



A graceful attenuate slightly arcuate Cadulus, gradually increasing 

 in diameter till the oblique aperture is reached. The shell is sub- 

 pellucid, white, quite smooth, posterior or apical orifice minute, 

 simple, round, thin, the mouth being roundly-ovate, with very oblique 

 margin. Two specimens, differing from any in the National collection.
