example of A. punctata. The people, however, led me to beUeve that another 

 "Culebrita ciega" occurred which was not Typhlops lumbricalis. The latter is 

 often called "vibora." 



Amphisbaena innocens Weinland. 

 W'einland, Abh. Sennk. naturf. gesellsch., 18G2, 4, p. 137, pi. 5. fig. 2. 



Weinland states that he captured three specimens near Jeremie, Haiti; and 

 at the end of the description says that one was sent to the Berlin Museum, — 

 whether before or after the description was written does not appear. At any 

 rate it is quite certain that M. C. Z., No. 3,624 and 3,625 are the other two speci- 

 mens of the three captured, since they bear the label "Jeremie, Haiti, collected 

 by Dr. D. F. Weinland." They were received when the Weinland collection 

 was purchased during Louis Agassiz's administration. 



Regarding the distinctness of this species from A . caeca I can only say that 

 both specimens have two instead of three scales behind the unpaired postmental, 

 and that their number of body rings is low, 212 and 213. Since these characters 

 fall within the range of what Stejneger (Rept. U. S. nat. mus. for 1902, 1904, 

 p. 677) has suggested is probably diagnostic for the species, there can be no 

 doubt but that there is now sufficient evidence as to the stability of these char- 

 acters to make it quite certain that this is a valid species. 



In the Zoological record for 1865 (p. 149) Giinther, after reviewing Gray's 

 Catalogue of the Amphisbaenidae, which appeared that year, makes the note 

 that "we understand that the A. innocens (Weinland) has been previously de- 

 scribed." Gray (Cat. shield rept., 1872, 2, p. 38), although admitting this 

 species to his list, repeats that it is "understood to be previously described." 

 It is difficult to understand how this apparently erroneous idea can have arisen, 

 unless some obscure publication has escaped all recent herpetologists. 



Since all the above was written Mann's collection has brought a typical 

 example from Manneville, Haiti. Tliis shows all the peculiar characters of the 

 types. 



Amphisbaena manni, .sp. nov. 



Type: — No. 8,645, M. C. Z., Cape Haitien, Haiti, W. M. Mann, collector. 

 Three paratypes from the same locality. 



This is the Haitian representative of ..4. caeca of Porto Rico. It resembles 

 this species in having a similar arrangement of head and cliin shields. The series 

 shows that this condition is quite unstable but probably equally so in A. caeca. 

 The number of dorsal and ventral segments of a single annulus of scutes is the
