Note on the Fossils yrom Kotah, Deccan. 



The ichthyolites above-described were forwarded to Col. Sykes by 

 Dr. T. L. Bell, in the summer of 1853 ; and in a letter dated 

 July 12tb, 1853, Dr. Bell states that these specimens were taken from 

 the same spot at Kotah* from which those previously sent were 

 obtained. 



The specimens of bituminous shale contain, besides the fish-remains, 

 fiome coprolites and some traces of plants. There are also four 

 specimens of impure limestone with fish-remains {Lepidotus and 

 JEchmodus) . 



Some small pieces of a reddish, friable, coarse sandstone or grit, 

 containing obscure traces of wood, accompany the above, and are 

 mentioned as having been obtained about 200 yards further up the 

 river, where this is the surface-rock, and rests upon limestone. The 

 specimen sent of the latter is similar to the limestone with fish- 

 remains above-mentioned, and to that referred to in the former 

 notices f. 



Dr. Bell also forwarded with the above several fragments of dark 

 day-slates, and of a black micaceous quartzy schist with a coarsely 

 wrinkled surface and obscure vermiform markings. These specimens, 

 he observes, "were collected fifteen miles N.E. from Kotah, at the 

 foot of a range of hills, 400 feet high, whose general direction is 

 parallel to the other hills at Kotah and in the surrounding country, 

 but with an underlying stratum of clay-slate, which has a dip directly 

 opposite to that of the underlying strata at Kotah. This clay-slate 

 is very extensive ; I traced it until it was lost beneath the sandstone 

 range. The layers composing it are extremely fissile and break up 

 into rhomboidal masses soon after exposure. I observed, while 

 tracing it, evidence of disturbance in the form of a fault in one case, 

 and a bend in another, separated from each other by about 800 

 yards."

[Plate XIII.] 



The fish-remains contained in the six specimens submitted to 

 me by Mr. Horner for examination are derived from not fewer than 

 sixteen individuals. 



With the exception of one mutilated tail, the posterior portions of 

 all are deficient. The cranial bones are for the most part in good pre- 

 servation; some of the fins are also well shown, more especially those 

 parts composed of hard spines. The teeth and scales are also in
