Original description: — '■'■Testa perforata, depresso-glohosa, radiato- 

 striata, nitida, ccvridescente-albida, antice rafescente, versus apicem 

 rufo-castanea, punctis plurimis hrunneis translucentihus quasi solata, 

 fascia unica castanea supra angulum anfractus ultimi usque ad 

 apieein decurrente, 1-3 ohsoletis suhtus ornata ; anfractibus 5, con- 

 vexiuscuKs, idtimo suhangulato, angulo antice evanescente ; spira 

 ohtusata ; apertura ohliqua, transverse ovato-lunata, periJieraatei^itus 

 fusco-castaneo, alho-marginato ; lahro recto, dejiexo, margine columel- 

 larl sid)rejiexo, umhUicuni fere tegente. 



" Diam. major 23, minor 18 ; axis 11 mill. 



^''Hab. montibiis Nilgherries Indite meridionalis (Dr. Jerdon). 



"I owe this species to the kindness of Dr. Jerdon, who sent it to 

 me with other interesting shells from the Madras Presidency, He 

 found it on the western face of the Nilgherries. I have a larger 

 specimen from the same source in bad condition." 



Animal (Plate LXXX. figs. 2 & 2 a). There are no shell-lobes to 

 the mantle ; the right dorsal lobe is small, the left long, narrow, and 

 continuous. Sole of foot not divided (fig. 2 a), but puckered and 

 wrinkled transversely. The mucous pore is overhung by a slight 

 blunt process (fig. 3), and the slit extends to the sole of the foot. 

 Pallial line distinct, above a broad peripodial margin. In the 

 generative organs (fig. 4) the amatorial is solid and cylindrical, 

 with a retractor muscle ; in the male organ there is a stout and 

 long caecum-like process, at the head of which the retractor muscle 

 is given off. The spermatophore is short and pear-shaped. The 

 teeth of the radula (Plate LXXXII, figs, 2-2 c) arc arranged : 



35 . 2 . 15 . 1 . 15 . 2 . 35 



52 . 1 . 52 



The central tooth is strongly tricuspid, the adjacent central teeth 

 are hardly tricuspid, only showing an exceedingly fine notch on 

 some of the teeth on the inner upper margin ; the laterals do not 

 decrease much in size towards the margin, and are evenly bicuspid — 

 in fact, very similar to the Macrocldamys form of the radula. The 

 dentition of N. solata is also similar in character to that as figured 

 by Semper of Xesta belangeri, tranquebarica, maderaspatana, and 

 ligtdata.
