60 Contribution towards the knowledge of snakes in Brazil 
through the eyes and extending on either side to the mouth, 
forward to the anterior edge of the frontal and back to 
the posterior angle of this scale; symphysial, anterior chin- 
shields and three first lower labials blotched with black. Anus 
situated in the light interspace of the 16th. and 1th. sets of 
rings. 
Dimensions — Total length 635 mm.; tail 37 mm. 
Habitat — Captured in December 1915 at «Fazenda Bonito », 
Bocaina mountains (State of São Paulo), valley of the Mambucabai 
river, at an adtitute of about 1.000 meters, 
Type — N.º 1.849 of the Butantan Institute snake collection 
(preserved im alcohol). This snake was offered in February 1921 
by MR. C. R. FISCHER, present draughtsman of the Institute, to 
whom I dedicate the species. 
Note: In the key to the Elaps species, arranged by G. A. 
BOULENGER (12), Elaps fischeri should be included in Section FEED 
HI — Seven upper labials, 3rd. and 4th. entering the eye; 
B. — Yth. upper labial well developed; rostral moderate, just 
visible from above: internasals much shorter than the pree-frontals; 
3 — Symphysial in contact with the anterior chin-shields. 
Elaps fischeri which, as far as I know, is the first species 
in this group assigned, to Brazil, is very allied to Elaps ancoralis 
BOULENGER, by the contiguity of the symphysial with the anterior 
chin-shields and by the disposition of the black rings on the 
body; it differs however from the same by the following cha- 
racteristics:
