Liasis fuscus n. sp.
One frenal, one anteorbital, two postorbitals. Rostral without pits. First supralabial with a shallow pit above; of the infralabials, the 9th, 10th and 11th, or the 10th, 11th and 12th with a deep pit. Nasal with a projecting angle at the posterior margin for reception of the frenal. Nasal groove directed straight backward. 11 supralabials, 16 infralabials. Body scales glossy smooth in 49 (forty-nine) longitudinal rows, ventrals 283, subcaudals 75, of which in the specimen at hand the 2nd, 3rd, 4th, 6th, 8th and 9th are undivided.
Above dark olive-brown, below including the upper lip dirty yellow; tail entirely dark brown and after loss of scales blue-black.
Total length 0.955; head 0.037; tail 0.140.
Port Bowen; collected by Mrs A. Dietrich, from the Museum Godeffroy.
Most closely related to Liasis olivaceus Gray, which however according to the description has much smaller scales, in 69 to 71 longitudinal rows.
=======================
Liasis maculosus n. sp.
Five to seven frenals in two rows; two anteorbitals and four postorbitals. Rostral without pits; nine to ten supralabials, of which only the first shows a pit. Thirteen infralabials, of which the 7th to 11th have a pit. Internasals oblong quadrangular, longer on the outer side than the inner; frontonasals pointed posteriorly, convex on the outer side. The anterior frontals are not larger than the frontonasals and either contact each other or are separated from one another by a small scale. The frontal is somewhat longer than wide, pointed posteriorly and bordered here by two parietals, each of which is scarcely larger than the supraocular. Sometimes the parietals are separated by a small scale. Body scales in 35 to 41 longitudinal rows.
Above light brown or yellowish-brown with five irregular rows of dark spots, of which those of the middle row are the largest; they are often very irregular and merge into irregular transverse or longitudinal bands. Underside yellowish, unspotted.

This species is very close to L. Childreni Gray, and the smaller number of supralabials, 9 to 10 instead of 14, and the absence of granulated scale rows beneath the frenals appear to be noteworthy differences.
