CRUSTACEA OF THE MEEGlJI AECHIPELAGO. 239 



finger presents two or ttree longitudinal rows of small, acute, 

 black-pointed spinules ; the immobile finger is armed with 

 similar spinules, partly arranged in longitudinal series ; the 

 under surfaces of the fingers are nearly smooth. The cheli- 

 pedes are covered with some yellowish hairs, which are more 

 numerous on the fingers, and arranged on the latter in small 

 transverse tufts, as well on their upper as on their under 

 surfaces. 



Each meropodite of the first and second ambulatory legs is 

 armed with an acute spinule at the distal end of the under 

 margin of its external surface near the articulation ; but other- 

 wise these joints are unarmed. The carpopodites of the first pair 

 of ambulatory legs present a longitudinal row of acute teeth on 

 their upper margins, of which the distal one is the largest ; those 

 of the second pair are only armed with a single acute spine at 

 the distal ends of their upper margins. The propodites are nearly 

 quite unarmed, presenting sometimes only a small acute spinule 

 at the distal ends of their upper margins. The slender, somewhat 

 arcuate dactylopodites of these two pairs of legs are longer 

 than the propodites ; those of the first pair are once and a 

 half as long as the propodites, and those of the second pair 

 are somewhat longer still. Their upper margin presents a 

 somewhat elevated, smooth, longitudinal ridge ; and the under 

 margin is armed with a longitudinal row of 7 or 8 black acute 

 spinules along the distal half. The dactylopodites terminate 

 in acute black points. The ambulatory legs of the first and 

 second pairs are clothed with small tufts of hairs along their 

 upper and under margins, those of the upper margins of the 

 dactylopodites are arranged along the inner side of the longi- 

 tudinal ridge. The legs of the two posterior pairs are also very 

 hairy. 



The coloration of this species is very characteristic. The 

 anterior part of the upper surface of the cephalothorax is of a 

 uniform pale colour and is not marked with longitudinal lines, 

 though it presents in some specimens a few small red spots. 

 The lateral sides of the carapace are a little reddish. The eye- 

 peduncles are of a red colour and marked along the inner margins 

 of their upper surfaces with a narrow longitudinal pale line, 

 proceeding from the cornea to the base ; another longitudinal 

 pale line proceeds at the outer side of the upper surface, from 

 the cornea, gradually tapering till near the base of the peduncle.
