^ Fig. 58 Comb scale of 



bearing a group of compound, finely bar- ^- cinereoboreaiis 

 buled hairs. A similar group also occurs at the anterior angle 

 which is less sharply defined, and also on the dorsal surface. Hairs 

 of the body mostly simple, those on the first and second abdominal 

 segments compound and weakly barbuled. Comb of the eighth ab- 

 dominal segment consists of 14 to 16 scales, each having a some- 

 what spatulate base and terminated by a stout spine, at the base 

 of the latter on either side is a much smaller spine followed by a 

 series "of still smaller, weaker ones. Anal segment, with a broad 

 dorsal plate extending nearly to the ventral line but not inclosing 

 the segment. Air tube is about two and one half times as long as 

 iDroiad, tapering rather gradually to the apex, with two posterior 

 pecten, each consisting of about 18 spines closely placed together 

 and four others at a much greater distance. Each pecten tooth 

 is stout and with one or two denticulations; dorsal surface of 

 the air tube with a double row of hair tufts, each consisting of 

 about four tufts composed of a pair of weakly barbuled hairs.
