THE GENERA AND SPECIES OF SYMPHYLA. 41 



(Java). (R. I. Pocock lias determined these specimens as 

 S. immaculata, and published the result and the localities 

 in the paper mentioned above on p. 33.) Furthermore, the 

 species has been captured on the island of Koh Chaug (Gulf 

 of Siam) by Dr. Th. Mortonsen ; under stones, January 7th, 

 12th, 15th, 1900; under plants on stones, January Gtli, 1900; 

 under an old stem of a tree, March 14th, 1900 ; in the wood 

 at the river Kloug Salakpet, March 15th, 1900, — in all 

 thirty-nine specimens. Finally, five specimens froui Bangkok 

 in the Brit. Mus. were collected by Capt. S. S. Flower. 



Remarks. — This species is rather closely allied to S. 

 caldaria, but differs by several small characters; the setse 

 on the distal half of the antennee are less numerous, but 

 especially those in tlie central whorl are a good deal lougei-, 

 the penultimate scutum less emarginate, the claws on the 

 posterior legs a little shorter and more robust, the first pair 

 of legs with the posterior claw shorter, and the front seta 

 considerably more robust. 



(3. Scutigerella plebeia, n. sp. PI. 3, figs. 2a — 2d. 



Material. — One badly-preserved specimen with some ap- 

 pendages, and many seta) broken off. 



Head. — Moderately broad with a conspicuous lateral angle ; 

 the longest seta in front of the angle seems to be lost, — if not, 

 it is only lialf as long as the breadth of the proximal antennal 

 joints. The central rod without visible frontal branches, and 

 terminating behind in a very faint triangular area, which 

 touches the posterior margin of the head. 



Antennse. — The major part of both antennas is lost; of 

 the one thirteen, of the other eleven joints have been pre- 

 served. These joints are simple, and their sette in the central 

 whorls are rather short. The secondary whorl begins below 

 on the ninth joint. 



Scuta. — The second scutum with tlie posterior margin 

 slightly convex near the middle ; the antero-lateral setse
