fauna ; the few specimens from isolated localities, namely (c) and (d) 

 above, are described separately under IV. 



By the kindness of Dr. A. Smith-Woodward and Dr. F. A. Bather, 

 of the British Museum, the writer has been able to make the fullest 

 possible use, for comparison, of the rich collections under their charge. 

 Similar facilities were accorded him by Prof. W. J. Sollas, Mr. C. J. 

 Bayzaud, and Mr. J. A. Douglas, at the Oxford University Museum ; 

 by Prof. A. M. Davies at the Imperial College of Science ; by Dr. 

 F. L. Kitchiu at the Museum of Practical Geology. To all these 

 gentlemen, and especially to Mr. Henry Woods, of the Sedgwick 

 Museum, Cambridge, the writer expresses his cordial thanks.

DESCRIPTION OF SPECIES. 



A. AMMONOIDEA. 



FAMILY: DESMOCERATID^ : 



GEN. PAEAPUZOSIA, Nowak. 



1. PAEAPUZOSIA sp. nov. ? hid. 



(PI. XIX, fig 2; PI. XX, figs. 1, !,.; PL XXIV, fig. 3.) 



? 1906. Desmoceras (Pnzosia) yaudama (Forbes) Boule, Lemoiue &

 Suarez." Ann. de Pal., vol. i, fasc. iv, p. 20, pi. iv, fig. 5 only. 



The writer has not seen the specimen upon which this description is 

 based ; but in addition to the measurements given below and to the 

 two photographs here reproduced, a plaster cast of a portion of the 

 inner whorls (PI. XXIV, fig. 3) was forwarded, the specimen itself being 

 too bulky to be sent. The measurements, according to Mr. S. H. 

 Haughton's note, accompanying the photographs, are as follows : 



Diameter . . . 670 mm. 



Height of last whorl . 325 [=48'5 per cent, of the diameter]. 



Thickness . 225 [== 33 ]. 



Umbilicus . 120 [=18 ]. 



The specimen was also characterised as " looking very similar to 

 one or other of the species of Desmoceras (Puzosia} described from 

 Madagascar " ; and since the inner whorls, according to the plaster 

 cast of the dorsal impression, show the ribbing and compressed aspect 

 of P. gaudama, Boule, Lemoine and Thi'venin * non Forbes, the 

 * Loc. cit., fig. 4 a of pi. iv, which, however, is more compressed.
