Clathueella lemntscata, Nevill, PI. VII, Fig. 11. 

 J. E. A. S. (Ceylon Branch), 1869. 



White, with one brown band just below the sutures and with a second 

 one towards the base of the last whorl, the latter fills the excavated fur- 

 row and shows also in the interior of the aperture, the columella also is 

 stained brown ; whorls seven, distantly latticed with very broad longitudinal 

 and transverse keels, forming oblong granules where they cross one another, 

 there are four of these transverse granulose keels on each whorl, the upper 

 one small and somewhat indistinct, the two middle ones very prominent, 

 the lowest one small, scarcely perceptible, almost hidden by the next 

 whorl ; the last whorl has five of these keels, the first smaller than the 

 others, then an excavated furrow as in Glathurella fusoides, Reeve, and in 

 Clathurella JBlanfordi, nobis. 



Long. 6i, diam. 1\ mil. 



In sand from Ceylon and Mauritius (nobis), Bombay (Rev. S. B. 

 Fairbank), and Gwadar in Persia (W. T. Blanford). 



We give a figure, from a Mauritius specimen, of this widely distributed 

 little species.

Clathueella contoetula, n. sp., PI. VII, Fig. 12. 



Shell globosely conical, somewhat peculiarly twisted or bent, suture 

 distinct ; white, with a pink tinge towards tbe top ; apex very obtuse, with 

 a decollated appearance ; whorls 6, longitudinally ribbed, ribs thick and 

 prominent, distantly transversely striated, so as to present a granulose ap- 

 pearance ; at the base of the last whorl several rows of small granules ; 

 columella peculiarly twisted, aperture narrowly contracted, outer lip thick, 

 in the middle bent inwards. This shell seems very close to Reeve's PI. 

 obtusa, the shape however is different, the aperture more contracted, &c. 



Long. 5i, diam. 2|- mil. 



Abundant in sand from Balapiti in Ceylon. 



(Coll. Indian Museum and H. Nevill.) 



Clathueella Blaneoedi, n. sp., PI. VII, Fig. 14. 



Shell cylindrically ovate, elongate, sutures rather indistinct, apex 

 sharp and pointed, a beautiful deep mauve colour throughout ; whorls 7 

 to 8, longitudinally and transversely ribbed, ribs very prominent, of equal 

 thickness, forming granules at the points of intersection, towards the base of 

 the last whorl an excavated furrow as in our G. lemniscata, &c. ; columella 

 short and twisted, aperture moderately wide, contorted, with a rather large 

 sinus, outer lip thickened with two or three granules just within the aper- 

 ture. 



Long. 5f, diam. 2-g- mil.
