nearest approach, to it is an undescribed species from the Litho- 

 graphic stone of Pappenheim." 



Numerous fish-bones were found associated with the scales ; and 

 probably the greater portion belong to Lepidotus also. But these 

 and the Crocodilian teeth and bones, which are also common in these 

 clays from Montserrate and Plantaforma, have not yet been system- 

 atically examined. 



Professor Owen, on a cursory view of the large vertebra figured 

 in PI. XVII. , suggested that it would prove to be a dorsal vertebra 

 of a Dinosaurian Eeptile allied to the Megalosaurus. 



Note on the Molltjscan Kemains from Montserrate. 

 By John Morris, F.G.S. 



The fossil shells, from the greenish sandy clay, from Montserrate 

 are — A cast of a bivalve (1 in. by 1-g-hi.) apparently belonging to 

 the genus Unio ; a smooth-shelled Neritina (rare) ; numerous small 

 Paludince; and several specimens of a larger Paludina, having a 

 smooth shell, subumbilicate, and showing four ventricose whorls, 

 deeply sutured ; also several individuals of an apparently new species 

 of Melania, which may be defined as follows : — 



Melania teeebeiformis, spec. nov. PI. XIV. figs. 3 a, 3 b, 3 c. 



Shell subulate, consisting of 7-8 flattened whorls, marked with 

 numerous oblique, somewhat prominent, rounded ribs, which are in 

 some specimens stronger towards the anterior part of the shell. In 

 some individuals the posterior part of each whorl is slightly raised, 

 making the suture more distinct. The last whorl is somewhat con- 

 stricted. The aperture is ovate. The lip of the columella is some- 

 what thickened and reflexed. 



Fig. 3 c is a smooth variety, with a less cylindrical shell. 



Note on the Fossil Entomostraca from Montserrate. 

 By T. Bttpert Jones, Esq., F.G.S. 



About seven or eight specimens only of Entomostracan valves, 

 not well preserved, are to be seen on the fragments of green clay, 

 containing small Paludince, from Montserrate, submitted to examina- 

 tion. The hinges of the valves are not exposed ; and other import- 

 ant features are obscure. The following appear to be distinct forms, 

 as far as the shape of the carapace-valves can serve as means of 

 judging. 



1. Cypres (?) conculcata, spec. nov. PI. XVI. figs. 13 a, 13 b, 13 c. 



Carapace suboblong, slightly incurved on the dorsal and ventral 

 borders, rounded at the ends, narrowest behind ; greatest convexity 

 of the sides at the posterior third. Surface of the valves smooth, 

 slightly margined (this, however, may possibly be due to pressure in 

 this specimen), and markedly pinched in at the middle of the dorsal 

 region, where there is a broad shallow sulcus with a slight swelling 

 before and another behind it.
