19'Jl.] MTBIAPODA Or THE "SliEVT EXPEDITION." 531 



Length about 50 mm. by 5. Anal legs 25. Head 4 mm. by 4|. 



Colour. Head and first segment ferruginous ; rest dull olive- 

 brown. Legs very pale, almost white. Pleural appendages 

 ferruginous. Sterna pale. 



Head. Length and breadth almost, equal. Surface slightly 

 punctated. Antenna? seventeen joints, reaching to four somites ; 

 end joints rather large, very distinct and pearl-like. The left- 

 hand antenna shows an individual malformation. The first four 

 joints are thick, then the antenna suddenly diminishes in Bize. 

 In the right antenna the diminution in size is gradual. 



Maxillary teeth. The outside one on each coxal plate is large 

 and distinct; inside there are two fused and indistinct, and 

 showing further imperfect division. The basal projection is 

 indistinctly toothed and somewhat cut away at the base. The 

 maxilipede shows a ridge edged with bristles from the claw to 

 halfway up the first joint ; the second joint has a projection on 

 the underside (PI. XXXII. tig. 94). 



The pleural appendages are long and show three spines at the 

 end and two some way clown. The anal legs have spines 

 4, 5, 1, 5. The last four sternal plates are prolonged in the 

 middle over the succeeding ones. The differences in the colour 

 and proportion (great length of the anal legs) and in the arrange- 

 ment of the spines render it questionable whether this specimen 

 should not be regarded as a separate species. 



There are two much younger specimens of the same species 

 from Tapelung and Bukit Besar. The anal legs of one have a 

 faint livid tinge at the end; the other has a dark greenish line 

 down its back.
