414: Mr. H. A. Baylis on Octopetalum, a 



zygomatic breadtli 37"5 ; nasals, diagonal length 37 ; inter- 

 orbital breadth 18'5 ; upper tooth-series (alveoli) 15"2. 



Hah. Near Lake Valencia, Carabobo, N. Venezuela. Type 

 from El Trompillo, S.E. of the Lake. Alt. 1300'. 



Type. Adult male. B.M. no. 14. 9, 1. 84. Original 

 number 80. Collected loth May, 1914, by Mr. S. M. 

 Klages. Presented by the Hon. N. C. Rothschild. 



This hare is evidently that referred to by Mr. Osgood * as 

 S. cumanicus in reference to a specimen from Maracay, on 

 the northern side of Lake Valencia. He gave exactly its 

 distinguishing characters, as compared with cumanicus, 

 orinoci, and allies, but did not consider he had enough 

 material to describe it as new. 



Now, however, the confirmation afforded by Mr. Klages' 

 specimen makes me think it should have a special name. 

 Its chief characteristic is its uniformly bufFy colour as dis- 

 tinguished from the more greyish tone, and especially the 

 conspicuous grey flanks of the Cumaua hare, while its greater 

 size readily separates it from that of the Orinoco. 



LIII. — On Octopetalum, a new Genus of Avian Cestodes.

The material upon which this account is based was found 

 among some parasitic worms collected in Nyasaland by 

 Dr. J. E. S. Old. They were sent by him to the Imperial 

 Bureau of Entomology, who kindly handed them to me for 

 determination, and allowed me to keep them for the British 

 Museum. 



One of the tubes contained Cestodes taken from the 

 intestines of a guinea-fowl, which, as the Bureau kindly 

 undertook to discover for me, was Avithout doubt an example 

 of Guttera edouardi, Hartl. These cestodes were of two 

 species, some of them proving to be specimens of Davai'nea 

 pintneri, Klaptocz, which was already known to occur in 

 another guinea-fowl, JVumida ptilorhyncha. It is now, how^ 

 ever, recorded for the first time, I believe, in guttera. 

 Among these there were also found three whole specimens
