Distira, they are. By the discovery of grooves in these teeth in specimens 

 of the former in the British Museum, the chief reason for considering the 

 two forms distinct was removed, and I went on to show that the only 

 apparent differences that remained, judging from Boulenger's detailed des- 

 criptions, affected the number of the supralabials (6 or 7 for spiralis and 7 

 only for brugmansi) and ventrals (270 to 334 for spiralis and 300 to 354 for 

 brugmansi) . I remarked that I found specimens labelled brugmansi in the 

 British Museum with 6 supralabials, and that the range of ventrals given 

 me for 65 specimens I had examined which I considered alike, was 282 to 

 373. 



As regards markings I showed that there was at least one specimen 

 labelled brugmansi in the British Museum with vertebral spots in some of 

 the interspaces, similar to those characteristic of the form labelled 

 spiralis.

DISTIRA SPIRALIS. 

 To show variations in the posterior labials (1 to 8) and temporal (T). 



An examination of the brood now before me confirms the above stated 

 opinions, for it will be seen (1) that the supralabials are variable, (2) the
