Another form of tooth, apparently of this genus, from the Eocene 
of the Punjab, has been named Capitodus indicus by B. Lydekker, 
Ptec. Geol. Surv. India, vol.xiii. (1880), p. 61, and Palseont. Indica, 
ser. X. vol. iii, (1886), p. 245, pi. xxxv. fig. 11. 
Stouter teeth, more deeply crimped but otherwise much 
resembling those named Trigonodon, have also been described as 
follows :—

Anterior teeth acutely conical, minute and clustered, with few 
large canines; hinder teeth rounded and molariform, in two or 
more series. Preoperculum fimbriated, not serrated. Dorsal fin

There are no fossils in the Collection certainly referable to this 
genus, and those described as follows are not generically determin¬ 
able :—
