﻿Sir P. G. Egertou on Fish from the Lias of Lyme Regis. 153 



2. Isocolum granulatum, gen. et spec. nov. — For elegance of form 

 this fish can vie with the salmon of modern times, its contour being 

 very similar. It bears the greatest resemblance to the Sauroid genus 

 Caturus, but in the absence of the teeth it cannot be assigned with 

 certainty to any particular family. 



3. Holophagus gulo, spec. nov. — A coelacanth fish, remarkable 

 for its resemblance, especially in the contour of the head, to the 

 Cretaceous genus Macropoma, and for substantiating Prof. Huxley's 

 demonstration of the persistence of type presented by this family, 

 which ranged from the Coal-measures to the Chalk. 



4. Eulepidotus sauroides, gen. et spec. nov. — This first represents 

 a genus uniting the Lepidoid and Sauroid families of Agassiz's 

 Ganoid order — the teeth and the tail being Sauroid in character, 

 while the fins are Lepidoid, and the scales partake of the characters 

 of those structures in both families. ~ 



6. " Note on the Geology of Port Santa Cruz, Patagonia." By 

 Cap^. T. Baker, Lieut. Royal 1ST aval Reserve. 



This note accompanied some specimens of fossil shells obtained 

 by the author from the cliffs of the western arm of the river Santa 

 Cruz, the stratification of which he described. The shells are for 

 the most part referable to the Tertiary species from Patagonia pre- 

 viously obtained by Mr. Darwin. 



7. " On the Jurassic deposits in the jST.AV. Himalaya." By Dr. 

 F. Stoliczka, F.G.S., of the Geological Survey of India. 



The author described the following strata as composing the 

 Jurassic rocks in the north-west Himalayas : — 



1 j . \a. Lower Tagling limestone. 



. la .... -j ^ Upper Tagling limestone. 



a t\ \c. Jurassic slates. 



2. Dogger { rf> Spiti shales> 



3. Malm ? e. Gieumal sandstone. 



The object of the paper was to show, in opposition to Mr. Tate's 

 assertion to the contrary, that the Indian Jurassic formation could 

 clearly be subdivided, and that in some measure the subdivisions 

 correspond with those of the European Jura. 



8. " On a true Coal-plant (Lepidodendron) from Sinai." By J. 

 W. Salter, Esq., A.L.S., F.G.S. 



The fossil described was received by Sir R. I. Murchison some 

 years ago. The author regarded it as an infallible indication of the 

 pesence of the true northern Coal-formation, with species like 

 those from the Erekli coal. The proposed name of the species is 

 Lepidodendron mosaicum. 



9. " On some Fossils from the Menevian Group." By J. W. 

 Salter, Esq., A.L.S., F.G.S., and H. Hicks, Esq. 



The authors, after describing the localities and stratigraphical 

 relations of the Menevian group, proceeded to describe the following 

 species : — 



Paradoxides aurora, Salter, represented by a few imperfect heads, 

 unattached pleurae, &c. Localities, Porth-y-rhaw and St. Davids. 



P. Hicksii, Salter. This species presents a singularly inter-
