1. The Homology of the Weberian Ossicles.

Zoological Survey of India.

of India.) 
The work, of which a summary is published here, was under 
taken at Lahore in 1918-19 under the guidance of my profes- 
sor, Lt.-Col. J. Stephenson, to whom my best thanks are due. 
At that time-I was engaged in the detailed morphological 
study of the Weberian apparatus in Cyprinoid fishes such as 
Labeo rohita, but my attention was diverted to the study of 
their homology by finding considerable variation in the struc- 
ture of the tripus. Since I have joined the Zoological Survey 
of India, pressure of other work has not left me much time 
to study this problem further. This short note is published 
Bridge and Haddon! have critically examined the views 
held by previous writers regarding the homology of these 
ossicles and after an exhaustive study of the anatomy of the 
Siluroid fishes have summarised their own views on the subject. 
For all previous references, therefore, one has to consalt their 
valuable paper. In the writing up of my descriptions I have 
‘adopted their nomenclature. :
