In spirit the upper surface of the head and body is dusky 

 and the belly is white 



Locality. — Only one specimei\ from Persian Baluchistan 

 (VV. T. Blanford's Persian collection) has been examined. It is 

 immature and the sex cannot be determined. 



The species differs fromG. persica, Berg (1913) in having the 

 upper lip fringed, in having no scales on the belly and in pro- 

 portions and colouration. In it the eye is situated almost in the 

 centre of the head, while in G. persica it is in the posterior 

 half.

Through the kindness of Mr. Tate Regan, to whom our best 

 thanks are due, we are now in possession of theoriijinal description 

 of Heckel's species. After a careful comparison of Dr. Annandale's 

 Palestine specimens with the description of Heckel's G. rufus 

 from Syria, I have not Ijeen able to find any specific differences. 



In G. nifus the air-bladder is well-developed and its length is 

 contained 2"/ times in the total length of the fish without the 

 caudal fln. 



Garra blanfordi (Boulenger).

While discussing the distribution and relationship of the 

 genus Discognathus, Annandale' pointed out the possibility that 

 the African species "may be degenerate rather than primitive." 

 He had then no African specimens for examination. I have now 

 dissected a specimen of G. blanfordi from Abyssinia in order to see 

 the air-bladder and the weberian ossicles and find the structure 

 of both to be of normal Cyprinid type. The air-bladder is fairly 

 extensive and is not covered by any fibrous coat. The weberian 

 ossicles and the bladder are of the normal Cyprinid type. It is 

 clear, therefore, that D. blanfordi is not degenerate in so far as the 

 air-bladder is concerned. The following are the measurements of a 

 specimen 35 mm. in length without the caudal : —
