Stat. 131. Anchoiage oft' Beo, Karakelang Islands. Reef. i specimen. 



The specimen is strongly contracted and measures hardly 25 mm. 

 in length ; the number of its segments is about 30. It is distinguished at 

 first sight from the species oi Pontogetiia, hitherto described, by its thick 

 dorsal feit, that entirely covers the elytra and also hides the greater 

 part of the paleae, which only with their distal end are emerging from it. 

 The paleae (Fig. 1) are of a pale yellowish colour and lack the golden gloss 

 of these bristles in Pontog. luida and other species; they are slightly bent, 

 terminating in an acute ape.x and on the convex side of their distal half 

 are i^rovided with two rows of small, alternating tubercles. Besides the 

 paleae the notopodium contains three kinds of thread-like setae, which 

 form the dorsal feit viz. (i) slender, bent, capillary bristles, (2) setae with 

 an articulated appearance, half as broad as the preceding, (3) much 

 thinner threads, which are only visible by high power. According to the 

 observations of CL.\p.A.RÈnE ^) and Potts -) the dorsal feit of Pont. chryso- 

 coina consists only of two kinds of setae. The ventral bristles (four in 

 each fascicle) are of a dark brown colour and have the usual bifurcated 

 apex ; their accessory tooth is rather small (Fig. 2). The head is provided 

 with two large, globular eye-stalks, bearing each a pair of eyes, the ventral 

 of which is two times larger than the dorsal one. The skin of the body 

 is densely covered with papillae.
