534 Miscellaneous, 



Rewah. They consist of a basioccipital and basisphenoid, with 

 minute fragments of the maxillary bone and a dorsal vertebra. 

 The evidence of the genus Parustichus, a crocodilian type from 

 Maleri, consists of similar remains rather better preserved, and 

 includes the articular part of the quadrate bone, a fragment of the 

 premaxillary, and what the author regards as dermal scutes. It is 

 considered that some other fragments indicate a Dinosaur ; but the 

 remains are not of that conclusive character that might be desired, 

 consisting of a fragment of a dorsal vertebra of Teleosaurian type, 

 a caudal vertebra, and a phalange. The phalange has a more 

 Dinosaurian aspect than the other bones. There are some teeth, 

 referred to the same type, which resemble the hinder teeth of Belodon 

 as well as Thecodontosaurus. 



The remains of Mastodonsaurus are said to consist of the right 

 supratemporal bone found in the Denwa group, on the Denwa 

 river, in the Satpura district. Other fragmentary specimens are 

 stated to be allied to Metopias of Von Meyer and Onpitosaurus of 

 Miinster. A portion of a maxillary bone shows teeth with folded 

 enamel, each having a quadrate base with a pulp-cavity. There are 

 also fragments of cranial bones, mandible, and vertebrae. All these 

 remains are of so fragmentary a character that more than ordinary 

 courage was needed to refer to them at all, and the conclusions 

 adopted are necessarily speculative. The volume concludes with a 

 list of memoirs which relate to these fossils, followed by a synopsis 

 of the Pretertiary Indian Vertebrata. 



MISCELLANEOUS. 



Some neiu Infusoria from American Fresh Waters. 



In the * Annals ' for February last, under the above title, the present 

 writer published an article in which a new genus of Infusoria was 

 formulated with the name Bijjiomastax, the word Biplomestoma, 

 which I had selected and written in my MS., having been cancelled 

 by the Editors under a misapprehension for which I gave them one 

 excuse, it seems, by my mistake in writing " Diphmastax " in the 

 explanation of the plate, and another by deriving Diplomestoma in 

 an utterly impossible way, according to the editorial note in the 

 April number of the magazine. Therefore, since Diphmastax is 

 preoccupied and the derivation of Diplomcstoma is offensive to the 

 purist, I withdraw it and substitute the name Dallasia, in honour of 

 Mr. W. S. Dallas, F.L.S., Assistant Secretary of the Geological 

 Society, to whom it affords me much pleasure to dedicate the genus, 

 the name of the species described thus hecoming Dallasia frontata 

 instead of Dlplomestoma frontata.
