upward *) and from which radiate numerous lines and series 

 of points. Base of dorsal not elevated. Anal and caudal very 

 small. Yellowish with a faint brownish marmoration. Length 

 of the single specimen known 79 mm.

D. 29 (29 3 1) 2 ); P. 13(13 14); A. 4; C. 10; Rings 17 + 32 

 (17+32 35); Subdorsal rings 2-f 6 (1+6). 



Rather slender, trunk heptagonal, tail tetragonal. Rings trans- 

 versely striated, their edges pronounced but smooth. Superior 

 cristae of trunk and tail discontinuous; inferior cristae of trunk 

 and tail continuous. Median cristae of trunk terminate at the end 

 of last trunkring; the superior cristae of tail begin, quite near 

 them, on the first tailring: both are therefore subcontinuous. 

 Head 6.6 in total length, about twice in trunk and one 

 quarter longer than base of dorsal. Eye more than 6 times 

 in head and about thrice in snout. Snout about equal to remaining 

 part of head, somewhat compressed, with a median crest ending 

 about in the middle of the concave interorbital space and with 

 a lateral crest ending in orbital ring, which is prominent but 

 smooth. Occiput somewhat concave but corrugated ; praenuchal 

 and nuchal shield corrugated and with a median keel. Oper- 

 culum somewhat inflated with a short basal keel, whereof 

 radiate numerous fine striae, their intervals punctured. Base of 

 dorsal not elevated ; caudal nearly twice as long as eye. Brown, 

 with a faint silvery transverse bar on the trunkrings; on the 

 tail a light transverse bar on each third ring; dorsal with 

 rather broad, oblique brown bands. Length 143 mm. 



Habitat: Celebes!; Moluccos (?). Malacca Straits, China, 



1) This is somewhat too strongly accentuated in our figure. 



2) The numbers in brackets are those given by DUMERIL and GUNTHER; our 

 diagnosis is made after a single specimen in the Leiden Museum, collected by 

 VAN DEI.DEN in Celebes. We have also some specimens in the Amsterdam 

 Museum at our disposition given by VAN DER HUGT and said to be collected 

 in the Moluccos, but we are not absolutely sure, that this was really the case. 

 We are not free from the impression, that this collector, as in olden times often 

 was the case, also collected on his homeward voyage round the Cape of Good Hope.
