MTEIOPODA OF THE MEEGUI AECHIPELAGO. 



295 



Hind half of each somite brown with reddish posterior margin ; 

 head, antennae, and first dorsal plate light brown ; legs clear yellow. 

 Somites smooth and shining. 



Lower lateral portions of the hinder half of each somite longi- 

 tudinally striated ; fore part of each somite concentrically striated. 



Belly- grooves oblique ; those on the central somites as long as 

 the two basal segments of the legs. 



Pirst dorsal plate not extending laterally below the succeeding 

 ones ; anteroinferior border rounded, with margin elevated and 

 thickened. The groove that marks this thickening extending up 

 to and beyond the outer margin of the ocular area; postero- 

 lateral portions striated. Forehead with median sulcus. 



Posterior somite produced into a short, slightly upturned 

 spine, projecting slightly beyond the anal valves. 



Anal valves with margins thickened and slightly compressed ; 

 sub-anal plate triangular, marked off from the posterior segment 

 by a groove. 



In the male the antennae are relatively longer and the margin 

 of the anal valves more convex than in the female. 



The anterior lamina of the copulatory organ produced below 

 into two processes, the inner of which is slender and styliform. 

 The upper slender portion of the anterior lamina is attached to a 

 small triangular plate, by which it is connected with the corre- 

 sponding portion of the opposite side. The posterior lamina, 

 viewed from the front, is seen to be dilated below, rod-like 

 above ; the inferior border of the lower dilated portion giving off 

 two processes, an external and an internal ; the external process 

 projecting downwards and outwards. To the rod-like upper 

 portion is attached the central portion of the copulatory organ. 

 This consists of a slightly curved, elongate piece, which below is 

 produced into an upcurled membranous expansion. At the 

 proximal end of this is a simple styliform process, the upper 

 margin of which is slightly serrated. This distal end of the 

 membranous portion is bifid and setiferous. Prom the outer 

 side towards the distal end springs a long curved spur. 



Pour specimens, three females and one male, from Sulliyan 

 Island. 



The species was described by Dr. Karsch from Tenasserim.
