The present paper is a g pemisites of my work on the 
vascular system of Varanus bengalensis, the account of the 
venous system having appeared in the “Proceedings of the 
Zoological Society of London”’ for 192

of Lacertilia was laid by Corti in 1847, in his work ‘De 
Systemate Vasorum Psammosauri grisea.” ave not seen 
his work in original but it has been referred to by several 
subsequent workers. Rathke (12) described the aortic roots 
of about 55 species of Lacertilia, including some of the genus 
Varanus ; and the same autho , (13) and _ Hochstetter 
(7) have described the main arteries of the gut in a number 
of species. Most of these observations are reproduced in 
'“Bronn’s Thierreich” by Hoffmann, in his account of the Reptilia 
(vol. VI, Abt. ii, pp. 990, 991). Beddard (1, 3, 4) has also 
made comparative studies of the vascular system of a number 
of Lacertilia. 
These descriptions, however, do not ng mained apply 
to the present species, Varanus bengalensis which ther 
are some very conspicuous features not so far fasted iu in ae 
other lizard. There is, therefore, — for the fol-
