INDIAN CYPRINID^. 



25. Ill consequence of the important connection between colour and 

 structure here pointed out, I am in some doubt as to the nature of four 

 small species described by Buchanan,* and figured in the collection of his 

 drawings at the Botanic Garden. Two of them have been figured in the 

 Gangetic Fishes, and one a second time in Hardwicke's Illustrations ; but in 

 the published figures, the peculiarity of the colours to which I allude, 

 and which seems to have been preserved in the original drawings has 

 been overlooked. They have the form of Cirrhins, but they are each 

 marked with a dark spot at the end of the tail, and the colours of the back 

 descend partially across the sides in bars as low as the situation of the lateral 

 line. I have added the species in question to the Cirrhins as Cirrlimoids, 

 until we know something more of them. Should they prove from the length 

 of the abdominal canal to belong to Sarcohorince as their colours indicate, 

 they will occupy a place between the Opsarions and the Loaches. 



26. The third sub-family AiMlopferhicB, consists of the old Linnsean 

 genus Cohitis, the Anahleps, PcEcilia, Lehias, Fundulus, Wlolmesia, and Cypri- 

 nodons, as well as two other genera, Platycara\ and Psilorhynchus, to be 

 described in a subsequent part of this paper. These fishes are all remarkable 

 for their long cylindric bodies covered with a slimy mucous, the absence of 

 spines in any of the fins, and the shortness of their alimentary canal. 



IMr. Gray has recently separated the Loaches with suborbitar spines from 

 those that are without these singular organs. I have endeavoured to find 

 farther reasons to strengthen this division, a single character being insufficient

+ Named by Mr. Gray as Buchanan's Balttora, which rather correspond with my Psilorhyn- 

 chus, Psil. variegatm being Buchanan's Cyprinus Balitora.
