Comment(communicated by J. Hallermann).

Diagnosis. Four species of the fasciatus subgroup include individuals that would fit the following description: external ear opening well developed; 5th supralabial below centre of eye; 26 - 28 longitudinal scale rows at midbody; 16 - 22 subdigital lamellae on 4th toe, and generally 3 - 4 enlarged nuchal scales on either side of midline. The four species are nigrolineatus, oligolepis, undulatus (including amboinse, aruanum, and dammermani) and brunneus and all occur in New Guinea.

S. brunneus differs from nigrolineatus and unduZatus mainly in colourpattern and size: brunneus has a relatively uniform brown dorsal coloration (Figure 6) and reaches a SVL of 87 mm whereas nigrolineatus has dark pigment concentrated in the dorsolateral line (Figure 3) and reaches a SVL of only 75 mm and l.l1ldu.Zatus has a dorsal colour pattern of light and dark crossbands and reaches a SVL of only 62 mm. S. oZigoZepis has a rather uniform colour pattern like brunneus, but it is a much smaller species (maximum SVL = 55 mm) and is not known to have more than 16 subdigital lamellae on the 4th toe (16 - 22 in brunneus).
