Dr. Russell and Mr. Home's Observations , &c. 71 
was once more attended to ; and the subjoined description and 
remarks were received in return. 
Among the specimens submitted to Mr. Home, was one of 
the Bodroo Pam, in the description of which, lately published,* 
I have misrepresented the orifices now in question as the nostrils, 
having entirely overlooked the real nostrils. 
While the anatomical disquisitions were going on, inspection 
was made into some of the numerous collections of serpents 
preserved in the museums in London. In the British Museum 
I was shown, exclusive of the rattle-snake and the Fer-de-lance , 
four or five colubers •f with lateral orifices; in the Leverian 
Museum, I found two or three ; in the Hunterian Museum, 
two colubers, J and three boas ; § and in that of Mr. Heaviside, 
one coluber. || 
The total found in the museums above-mentioned, (exclusive 
of the rattle-snake,) were ten or eleven colubers, and three boas; 
which, added to five colubers in my own possession, amount to 
eighteen or nineteen subjects furnished with lateral orifices. 
It appears, on the whole, that the lateral orifices have hitherto 
been found only in venomous serpents. 
That (exclusive of the rattle-snake) they have been found in 
fifteen or sixteen species of colubers, and in three of the genus 
boa. 
That they have not as yet been discovered in any of the genus 
anguis. 
Mr. Home's investigations have clearly established, that these
