CEETACEOUS SPOXDYLOZOA 
(;r> 
PISCES. 
Sir Pliilip J. Egei’ton described in vol. I of tlie Quart. Journ. Gcol. Soe., 
London, (reproduced in Trans. Geol. Soc., vol. vii, p. 89 et seq.), the following 
species ; — 
Enchodns serratus, Eg. ; SphcBrodns i'uffnlosus, Eg. ; Corax pristodontus, Agas- 
siz; C. Eg. ; Otodus? marginatus,'E^.-, O. basalis, 'E^.\ O. nanus, Eg.; 
0. divergens, Eg.; 0. minutus, Eg.; Oxyrlima triangularis, Eg.; Lanina compla- 
Eg. ; L. sigmoides. Eg.; Odonlapsis constrictus,'Ei".\ O. oxyprion,!^,^. 
I sliall very briefly notice these in a somewhat similar order, adding a few more 
species. I do not need to repeat the great uncertainty in the determination of these 
stray relics, and will, therefore, not attempt to characterize the genera.

•A single tooth in the collection exactly agrees in the general squarish form, 
moderate convexity, and in the thickness of the enamel bands with the European 
species ; the sharp edges of these enamel bands arc very minutely crenulated, as is 
usually the case in this and most other species of the genus. The exact locality 
of the specimen is not recorded, but it was togetlier with a small fish bone of quite 
similar preservation, and this leaves but very little doubt that both are from cast 
of Olapaudy in the Arrialoor group. 
In Europe Et. latissimus is one of the most common species of the middle 
and upper cretaceous beds. Upper Greensand and Chalk. 
2. SPII.ERODUS RTJGIiLOSUS, Eg. PI. XII, Pig. 17. 
Sir Philip Egerton figures (Quart. Journ. Geol. Soc., Lond., 1G7,) a few 
SphcBrodus teeth, which, he says, are distinguished from otlier allied ‘forms by the 
wu-inkled or shrivelled appearance of the superficies.’ The specimens are from 
Pondicherrv.

3. Pycxodus ? sp. PI. XII, Pig, 18. 
A single fragment of a jaw from the Ootatoor beds east of Ootatoor is in our 
collection. It has a single series of four teeth, the last being very small ; the 
penultimate is largest, longer than broad, sloping posteriorly ; the two following are 
shorter than broad and squarish, depressedly convex above. The specimen evidently 
belongs to some Pycnodonte fish.
