Produrtus Purdoni (Davids). 



Op. Cit. p. 31. PL II. fig. 5. 



Zeawan in Kashmir and Rotta Roh in the Punjab. In a series of 

 specimens of P. Humboldt ii and P. Purdoni, it is quite impossible to 

 decide where one species ends and the other begins. 



Product us Flemingii (d'Orb.) 



Syn. P. longispinus (de Verri) and P, hiatus (de Vern.) 



Journal, Geological Society, Vol. XVIII. p. 31. PL I. fig. 19. 



Davidson's figure does not show the enrolled and horn-like ears so 

 well defined in our specimens. 



M. de Vernueil regards the Rotta Roh specimens as a well defined 

 variety ; see his note. 



Found at Zeawan and Zowoor and in the Rotta Roh. 



Productus Boliciensis (iVOrb.) and P. aculeatus f (Martin). 



See M. de Vernueil's Note. 



Found at Zowoor and Zeawan in Kashmir.

The specimen of the larger valve is from the Rotta Roh and the 

 other two from Zeawan in Kashmir ; they may be different shells. 

 The larger valve resembles the Productus Purdoni, but the spines are 

 fewer, better defined and less slanting towards the margin. The other 

 two specimens are remarkable for the excessive length of the thread- 

 like spines and for some complications in the hinge. 



Crustacea. 



Eurypterus f Limulus ? sp. PI. V. fig. 4. 



Claw of a Crustacean, belonging apparently to one or the other of 

 the two genera above. It was found on a slab which had been worn 

 by running water, so that a horizontal section of the claw is produced. 

 The same slab was full of Atliyris Buddliista (Verch.), Productus 

 Flemingii (D'Orb.). P. Aculeatus, Fenestella Syhesii (deKon.) and 

 Vincularia Multangularis (Patlock). 



The tegument is smooth and pierced by pores, which are seen 

 vertically sected on the margins of the claw, and appear like dots 

 where the tegument is not worn off. The tegument forms septa in 

 the upper mandibule, but none in the lower. The ends of the 

 mandibules are hooked. There are no traces of teeth on the internal 

 margin of the claw. No other part of the animal could be found.
