Peters, Monatsberichte K. Akad. Wiss., Berlin, 1880, 232. 



Subspecies lineatus Cope. 



This form agrees exactly in pholidosis with Peters' description, above 

 cited, of specimens from San Paolo, but diSers much in coloration. It 

 presents five longitudinal brown lines on the upper surface which mark 

 the third and fourth, the fifth and sixth, and the median rows of scales 

 respectively. In the adult, the line on the fifth and sixth rows is obsolete. 

 The inferior surfaces are immaculate, except that the black collar is visible 

 on the sides of the neck, from below. In the form erythronotus, the gas- 

 trosteges have black centres, according to Peters. 



37. Rhynchonyx ambinigeb Peters, Monatsber. Berlin Akad. Wiss., 



1869, p. 437. 



Subspecies vittatus Cope. 



This form differs from the typical form described by Peters, in having 

 longitudinal color bands. These are dark-brown, and are located on the 

 fourth, sixth and median rows of scales respectively, occupying only the 

 middle of each row. The space between the sixth rows of opposite sides 

 is pale brown ; external to the sixth row and below, dirty white. The en- 

 tire coloration is so like that of the young of Apostolepis erythronotus line- 

 atus, as to be a case of mimetic analogy. 



The present specimen confirms the correctness of the locality given by 

 Peters. 



38. Tantilla pallida, sp. nov. 



Postocular plates two, labials seven, the posterior elevated and separated 

 from the parietal by one and a part of another temporal. Postnasal and 

 preocular plates well separated. 



Characters normal. Postnasal bounded below by first labial, behind by 

 second labial, which reaches frontal. Preocular deeper than long. Third 

 and fourth labials bounding orbit, the latter also bounding inferior post- 

 ocular below. Fifth labial higher than wide ; the sixth of equal height, 

 which equals the middle ; the seventh largest of all, a little higher than 

 wide (or long). A large temporal bounds the fifth and sixth above, and a
