Walker desjcribed his species as having the " fore wings 

 greyisli, ferruginous at tliehase ; veins ferruginous, nodose," 

 Aviiereas in his type the tegmiiia are also very distinctly 

 ferruginous on the apical areas, as in Funkhouser's figure. 



XXXVI II. — Oil some of the Extemal Structural (liarocters 

 of the Striped Hyanui (Hysena hyaena) and related Genera 

 anil Species. By li. I. Pocock, F.R.S. 



This paper is based primarily upon tlie carcase of a female 

 example of Hycena hyana, from India, uliich died in the 

 Zoological Society's Gardens in Dec. 1915. Of the other 

 species of Hyaenas I have seen no fresh specimens ; hut in 

 1908 I made some sketches of the anal pouch and glands of 

 an example of Froteles cristotns. These I take the ojjpor- 

 tunity of reproducing. Unfortunately, no notes were made 

 of other external features of this animal. 



The Facial Vibrissa and Rhinarivm. — The facial vibrissas 

 of Hyrona hyana, as in all iEluroid Carnivora^ except the 

 Pelidse "^, consist of the normal number of tufts — namely, 

 the mystacial, superciliary, two genals, and the intcrramal. 

 The latter consists of about four well-developed brisths, and 

 each of the two genal tut'ts of approximately the same 

 number. Tiiese tufts are set rather close together near the 

 middle of the cheek, the inferior of the two being above the 

 posterior corner of the mouth. All the vibrissae may be 

 described as of medium length and considerable thickness. 



In living examples of the Spotted Hyaena [Crocuta 

 ciocvta) the corresponding tufts of vibrissae are quite 

 apparent, and on a dried skin of a Froteles from South 



* In tliis family the interramal tuft is always absent, as I have else- 

 where recorded (P. Z. S. 1914, ii. p. 901).
