about half its own length from base of fang; second dorsal about 

 half as long as first and twice as far from first as from third ; 

 space between third and fourth nearly as great as between second 

 and third, and about twice that separating remaining diminishing 

 series. First of ventral twelve or thirteen teeth situated not far 

 from base of fang, much shorter than first dorsal but much stouter 

 than four following ventrals, which are subequal ; space separating 

 first and second ventrals about twice as great as the two following 

 spaces ; remainder in diminishing series. Third ventral situated 

 shghtly behind second dorsal. Fang shorter than basal joint, un- 

 armed. 



Male. Chelicerae longer than carapace, with inwardly curved 

 and simply pointed subapical spine. At base of fang on inner 

 side above, a strong acuminate tooth at right angles to chelicerae 

 above and a little in front of first dorsal and of about equal size 

 with it ; behind this another tooth about twice as large, strongly 

 curved forwards, above and a little behind second dorsal. First 

 six (about) of dorsal ten teeth about equal in size and spacing, 

 except that the first two are somewhat nearer together than the 

 rest ; posterior teeth in diminishing series. First of ventral dimi- 

 nishing series of six teeth as large as and situated slightly in front 

 of first dorsal ; space between first and second about half as great 

 as subequal spaces between second and fifth ; space between fifth 

 and sixth much less. Second ventral situated between second and 

 third dorsals. Fang unarmed.

From Amboina. Lateral eyes much closer together than 

 medians. 



Female. Chelicerae about as long as carapace, with a low 

 obtuse tubercle on inner side near base below ; a small tooth at its 

 base on outer side; a subcylindrical, abruptly acuminate and 

 subobtuse tooth at its apex on lower side. First of dorsal 

 nine teeth strong and subsinuate, situated at base of fang. Second 

 dorsal not much longer and scarcely stouter than first, twice as 

 long as third, between twice and three times as far from first as 

 from third; third nearly twice as far from second as from fourth, 

 and opposite lifth or sixth ventrals. First six of ventral 

 twelve teeth of about equal size and almost equally spaced, the 

 remainder in diminishing series. Fang much as in T. genicnlata. 



ilale. Chelicerae more slender than in female, with long strong- 

 ly curved and simply acuminate dorsal subapical spine ; also a small 

 subapical ventral tooth, situated in front of the ventral series. 

 First of nine dorsal teeth moderately long, slightly sinuate, directed 

 forwards and inwards ; second slightly longer but less strong than 

 first and scarcely half as far from it as from third, though further 

 than third is from fourth; remainder ii: diminishing series. First
