broad at base, slender and slightly bifid distally. A stout conical 

 tooth is situated just below its base and another some distance 

 further back, much as in T. gracilis but of more nearly equal size. 

 The dorsal series of teeth contains about five onh', all minute, 

 situated much further back, the first of them being about 

 opposite the fifth and sixth ventrals. The first two ventrals are 

 situated close together at the base of the fang, the second larger 

 than the first and nearly as large as the two large conical teeth on 

 the dorsal surface; the remaining five are subequal, both in size 

 and spacing, except the last one or two which are smaller than the 

 rest but little if any closer. 



It is possible that this may prove to be only a subspecies of 

 T. pnclla from Tharrawad}-, from which it is distinguished chiefly 

 by having a bifid subapical spine in the male instead of an acu- 

 minate one. The only Burmese specimen I have seen is a female ; 

 but its eyes are as shown in fig. ig with the laterals much more 

 widely separated than the medians instead of equally so. 



Tetragnatha moulmeinensis, sp. nov. 

 Fig.. 2. 



Locality. — Moulmein, a single female. 



Much longer and slenderer than T. inackenziei, with long 

 divaricate chelicerae. Total length 

 about 12 mm., carapace about 3 

 mm. 



The carapace is more strongly 

 rounded in front than in T. 

 iiiackenziei, and the two rows of 

 eyes are more strongly curved in 

 consequence. The ocular quad- 

 rangle is slightly wider in front 

 than behind and slightly longer 

 than wide. The posterior eyes 

 are of about equal size and 

 about equally distant (a little 

 more than a diameter) from each 

 other. The anterior eyes are 

 widely separated from them, the 

 small laterals even more so than 

 the large medians. 



The chelicerae are about as long as the carapace, with a mi- 

 nute denticle on a low obtuse swelling on the outer side below. The 

 first dorsal tooth is slightly smaller than the first ventral ; both 

 these teeth are situated at the base of the fang and are followed 

 after an interval, which is longer in the dorsal row than in the 

 ventral, by other teeth in descending series, those of the dorsal 

 row being larger than those of the ventral and also extending further 

 back. The fang is simple and unarmed.
