(2) With two rows of tubercles. 



Some at least of the abundant casts from Kirimalai show the 

 two rows of tubercles very distinctly. But for this, they might be 

 identified with S. nodosus Sowerby, which they closely resemble in 

 shape ; the holotype of that species does not seem, however, to 

 have the second row, although the bad state of preservation makes 

 its absence uncertain. 



Two bituberculate strombs from Minihagalkanda may best be 

 compared with S. spinosus Martin, from the Miocene of Java. 



Semicassis spp. 



Pour fossils from Kirimalai are referred to the genus Semicassis. 

 One of these (Brit. Mus. G. 27051) retains the test, and, although 

 the adherence of intractable matrix somewhat obscures the shape, 

 it agrees very closely with the recent Semicassis boolei/i (G. B. 

 Sowerby), from the Andaman Islands. 1 It also resembles S. rem- 

 bangensis (Martin), a Java Miocene fossil, but is rather larger 

 than that species. 



The other three are internal casts, and therefore very difficult to 

 name. One of them agrees in proportions with the testiferous 

 specimen, and might be the same species ; but it matches equally 

 well with S. phillipsi (A. & H.), from Sind, and indeed with other 

 fossil casts. The remaining two certainly belong to a different 

 species, being decidedly narrower (breadth =3/5 of length instead 

 of 4/5) : they agree very well with S. sculpta (J. de C. Sowerby), 

 from Kach, and also, except in their larger size, with $. (Gasmaria) 

 bonneti Cossmann, from Karikal. 



Conus brevis J. de C. Sowerby. 



In Grant, Trans. Geol. Soc. ser. 2, vol. v, pt. 2 (1840) pi. xxvi, fig. 33. 

 Badly preserved specimens, referred without much doubt to this 

 Kach species, are fairly common at Minihagalkanda, where the 

 largest measures over 100 mm. in diameter at its broadest, and was 

 probably 150 mm. in height. But a solitary specimen from Kan- 

 kesanturai, at the other extremity of the island, the only fossil 

 recorded from that locality, is even larger, the diameter being 

 about 160 mm. Sowerby mentions the large size which this 

 species attains in Kach. At Kirimalai no such large form was 

 found, and none of the small Cones can be safely referred to this 

 species.
