OV SOUTHEEN INDIA. 485 



On page 182 add description of the following Indian new species— 

 THETIRONIA, StoliczJca, 1870, (see p. 158). 

 Thetironia ignobilis, StoliczJca, PL L, Fig. 3. 



Th. testa rotundate ovata, inflata, cEquilaterali, valvis tenuissimis, in superficie 

 concentrice striatis, et radiatim minute punctatis ; sinu palliali profunda, postice 

 angustatim fere usque ad apicem umbonis extenso ; valva dextra dentihus cardinalihus 

 duohus approximatis, et fossula laterali postica, remota, v. sinistra dentihus cardina- 

 libus trihus, suh-cequalibus et uno minimo postico, instructis. 



Only two specimens of this interesting species were contained in the old 

 Madras collection. Impressions of the shell indicate that it must have been very 

 thin, concentrically marked with minute strige of growth and radiately punctated. 

 The pallial impression, or at least what is taken as such, is perfectly distinct ; the 

 posterior sinus reached almost to the end of the beak. The muscular scars are 

 ovate, marginal, placed rather high up towards the beaks. The left valve shows 

 impressions of three closely approximate cardinal teeth, the median is largest, 

 directly under the beak, and may have been bifid, the two others slightly prolonged 

 laterally; there is besides a distinct impression of a somewhat remote posterior 

 lateral pit, but no distinct anterior lateral pit or tooth is traceable. The right 

 valve indicates two very approximate cardinal teeth (or three fossets), and a very 

 minute posterior lateral tooth. The character of the shell, its ornamentation, and 

 partially also the position of the cardinal teeth, most markedly resembles that of 

 Fimhriella (see p. 24i6), and it will be interesting to see in what relation these two 

 genera, as now accepted, stand to each other. 



Locality.— ?QnAiQ)iQYT J, The two specimens from which the above notes 

 were derived have been received from Madras. They are in a bluish grey siliceous 

 sandstone together with fragments of Antale Arcotinum, Eorbes, and some species 

 of Anisoceras, 



Formation.'—'^ Valudayur group.

16. Veleda, Conrad, 1870, (Am. Journ. Conch., VI, p. 74). Ovately 

 elongated, tumid, posteriorly ridged from the umbo, concentrically striated on the 

 surface, equivalved; ''left valve with a v (? A-) -shaped cardinal tooth under the 

 apex and three compressed teeth, posterior one elongated and parallel with the dorsal 

 margin, cardinal plate channelled, deeply so anteriorly." Type, V, lintea fCardium 

 linteum, Conrad, Journ. Acad. Nat. Sc, Phil., 2nd ser., vol. iv, p. 278, pi. 4i6, 

 fig. 17). The description of the hinge-teeth of the left valve appears to indicate 

 a relation of this genus to Cyprina, in which the median cardinal tooth is largest, 

 as in Cicatrea (see pi. x, fig. 2) ; but the statement is not clear whether by the
