This species is evidently nearly related to the Leposoma reticulatum of 

 O'Shaughnessy {Ccrcosaura reticulata O'Sh., Proceedings Zool. Society 

 London, 1881, p. 230). It differs in not possessing the following charac- 

 ters of that species, as described and figured. In L. reticulatum there are 

 two parietal plates on each side ; abdominal scales are rounded in pos- 

 terior outline, and in only eight rows, while they are in ten in L. picticeps ; 

 in having an azygous marginal anal instead of two, and in having a stripe 

 on the body, and the tail differently colored from the back. The type 

 of L. picticeps is a considerably larger animal than that of the L. reticu- 

 latum.

 Mr. O'Shaughnessy finds these supposed species to be identical. Dr. 

 Gtinther having established a new genus (Monoplocus) for the species 

 on the supposed absence of femoral pores, I did not think it worth 

 while to compare my specimens, in which they are numerous, with the one 

 described by Dr. Gunther. Mr. O'Shaughnessy has discovered that 

 Giinther's type possesses the pores.

Tail subround, without crest. Ventral scales small, smooth ; dorsal 

 scales minute, rough. Occipital scale small, well separated from supra- 

 orbitals ; the latter separated from each other by three rows of scales, 

 and not continued as a larger row anterior to orbit. Interorbital region 

 concave ; facial rugse obtuse, separated by a concavity. Facial scales 

 small, keeled, about twenty longitudinal rows at the middle of the 

 muzzle, and ten in the facial concavity. No distinct canthus rostralis, 

 and but two canthal scales distinguishable from those of the muzzle in 

 size. Supraocular disk embracing a dozen scales of unequal sizes, and
