ORIENTAL COLLEMBOLA. 87 



developed, and ouly noticeable on the ventral aspect. The second 

 joint the longest ; the fourth joint with a small trilobed apical 

 sense-orcian (fig. 10). 



Trunk. — The segments reliited to one another in length as 

 4:7:7:6:6:6:6:7:6, and provided with lateral tufts of 

 long setfe. The postero-hiteral margins of the fifth abdominal 

 segment produced into a setigerous protuberance on either side ; 

 the sixth abdominal segment with a pair of such ])rotuberances 

 on each side (fig. 12). 



Leys. — Short and subequal. The superior claw provided 

 with a single tooth on the inner margin near the base. The 

 inferior claw probably represented in a vestigial condition by a 

 small basal process (fig. 11). 



Coloration. — Scarlet when alive (Annandale) ; specimens in 

 alcohol are white. 



Length 1-5 2-25 mm. 



Eight specimens taken on bats'-dung in total darkness in the 

 Khayon Caves, near Moulmein, Lower Burma {y. Annandale, 

 March 7th, 1908).

Dr. Annandale informs me that the Khayon Caves are of no 

 great extent, though their inner parts are quite dark. There are 

 no features about Neanura pudibunda that point to its being a 

 true cave form, and most probably it is only a recent migrant 

 thither. 



* Neanura intermedia, sp. n. (PI. VI. figs. 13, 14; PI. VII. 

 fig. 20.) 



Tuhera corpoi-is desunt. Unguiculus inermis. Organa post- 

 antennalia nulla. Ocelli in lUroque latere capitis 2. Color coraliuia. 

 Long. 2 mm. 



This species diflfers from Neannra corallina, sp, n. in the absence 

 of doi*so-lateral protuberances from the body, and in possessing 

 longer sette to the antennae. Fi^om Neanura ]mdihunda, sp. n. it 

 difters in the number of the eyes and in the absence of the tooth 

 from the inner margin of each of the claws of the feet (fig. 14). 



It resembles Neanura corallina very closely in the important 

 structural features of the claws of the feet, the number of the 

 eyes, and the absence of post-antennal organs. It resembles 

 Neanura pudibunda in possessing two pairs of terminal setigerous 

 protuberances to the abdomen, in the absence of the dorso-lateral 

 protuberances from the abdomen, in the length and general 

 disposition of the setfe on the antennae (fig. 13), and in the 

 general foi-m of the body. It is thus intermediate in its characters 

 between the two preceding species of the genus, though it differs 

 from both in the above mentioned features. 



Colour. — Coral-red ; in alcohol specimens quite white. 



Tjength 2 mm.
