In Mr. BlanforcFs report on the Cretaceous roeks^ among other 

 notices of the Cephalopoda found in those rocks, two species have had 

 names attached to them as new, but have not been described. These 

 are Ammonites Tamulicus, p. 118j and Am, Madmspatanus, p. 92. 



Of these the former. Am. Tamulicus, is identical with a species 

 ah-eady described by Roemer from Texas (1849) under the name of 

 Aiti. Guaclaloupos. (See Palseontologia Indica, Series III, p. 90.) The 

 latter species. Am. Madraspatamis (which name has been retained) is the 

 species originally referred by Professor E. Forbes with a query to the 

 species Am. Juillcti of D^Orbigny, but from which it is certainly distinct. 



At various places also throughout the report Avn. Mantelli is quoted. 

 In most cases this is erroneous, much confusion between this and allied 

 species having been admitted by the author of the report. (See Pal. 

 Indica, Series III, page 83.) 



Again, at page 141, it is stated that one of the shells from near 

 Ninnyur is identical with Tunitella prcelonga, Hislop, from the Rajah- 

 mundry beds. More careful comparison shows that this is not so. 



The reader is requested to note these corrections.
