144 ALBATROSS EXPLORATIONS, REPTILES COPE. 



Ground-color gray. A row of six or seven blackish-light-bordered 

 spots on each side of the median line. Oue of these pairs is between 

 the orbit; one on the interscapular, aud one on the sacral regions, 

 and four or five small ones on each side of the urostyle. Two spots 

 posterior to each orbit, the inferior much the larger, and extending 

 posteriorly to the humerus, and in line anteriorly with a band on the 

 canthus rostralis which extends to the upper lip. A dark triangular 

 spot below the eye. Inguinal gland anteriorly light, posteriorly black. 

 Limbs cross-banded (four bands on tibia) ; inferior surfaces immaculate.

The extreme reduction of the second anterior digit is a remarkable 

 feature of the individual which represents this species. The character 

 appears to be normal, but the first finger on one of the hands is also 

 abbreviated, though to a less degree than the second digit. This is 

 clearly abnormal, since it is unsymmetrical, but it may be an imperfect 

 expression of the tendency so distinctly marked in the second digit.

The species referred to Aporophis in., are generally more slender than 

 the typical forms of Opheomorphus in., but they can not be retained in a 

 distinct genus. Lota, 15130.
