Loc. ? 



A siugie female with ova; length 16 mm. 



Of the teeth on the upper edge of the rostrum in this specimen, 

 only the proximal eight and distal three are clearly separate, the 

 intermediate teeth being represented by a rather ill-defi.ned 

 serrated ridge; on the under edge are nine distinct teeth. The 

 whole rostrum is slightly curved downwards, and the tip is abrupt 

 and blunt. The eggs moderately large, about 1 mm. in length and 

 oval.

Loc. Eiver Petwi, Tale Sap. 



Two specimens, very damaged, one without antennae, eyes, and 

 only one or two pereiopods, the other without pereiopods. 



These two individuals seem to belong pretty certainly to this 

 species, though their mutilated condition causes some difficulty in 

 deciding their identity. 



The rostrum reaches nearly to the end of the autennary plates ; 

 its proximal portion is straight, its distal portion deflexed, rising 

 again at the lip ; above are 15 small forwardly inclined teeth, of 

 Avhich to or three are on the carapace, while the 15th stops short 

 of the tip by a considerable interval which is unarmed ; the tip 

 itself is markedly bifid, and the under edge bears 6 teeth. Anten- 

 nary peduncle barely reaching the middle of scaphocerite ; the 

 antennary tooth double, the lower portion being more prominent 

 and spiniform. The carpus of the 2nd leg is much longer than 

 broad and a little longer than the hand ; the other legs are unfor- 

 tunately broken at the carpus. The telson appears to have only 

 four spines on its hinder edge, of which the two outer are much 

 smaller than the two inner.

Loc. Inland sea near Singora. 250-300 individuals, mostly 

 females with ova. 



In regard to the locality it is necessary to add that the label in 

 this instance was almost undecipherable, sufficient indications alone 

 remaining to show that the specimens came from either Tale Sap 

 or Tale JN'awi. Tale Sap is an inland sea just above the town of 

 Singora, Tale Nawi a lake at the head of Tale Sap, and connected 

 with the latter by a small strait. As regards the salinity of the 

 water, Mr. Laidlaw informed me that Tale Nawi is quite s\^■eet,
