SYNALPHEUS HERRICKI, new species. 



The tridentate portion is distinct from the rest of the frontal mar- 

 gin, to which it is united by rectilinear borders; the three teeth are 

 approximately equal in length, the rostrum a little narrower than the 

 lateral teeth, which are at least as long as wide at the base, and 

 usually longer. 



The articles of the antennule are as 2, L4, 1; the stylocerite reaches 

 the distal third of the basal article. 



The superior angle of the basicerite is obtuse; its lateral spine 

 reaches to at least the middle of the median antennular article; it is 

 1.5 times thicker than the spine of the scaphocerite, which bears no 

 trace of a scale; it is usually, also, very slightly longer, but it may be 

 only equal to it ; the tw^o spines are straight and parallel. 



The large carpocerite exceeds the antennule by the length of the 

 distal article; it is a little concave, cylindrical, 5 times as long as wide 

 in the males, or 4.7 to 4.8 in the females. 



The proportions of the large chela are very similar in the two 

 sexes: Fingers 1; total length 3.25 to 3.4; height 1.33 to 1.35; the 

 ratio is L. : H.=2.42 to 2.5 : 1 ; these figures apply to the males; in the 

 females they become, respectivelj', 1, 3 to 3.2, 1.2 to 1.35, 2.3 to 2.5; 

 the large chela in the female is generally proportionately broader, 

 with the fingers a little longer; the superior margin of the meropodite 

 is convex and unarmed ; it is 2.2 times longer than wide. 



In the male the proportions of the small chela are : Fingers 1 ; 

 total length 2.8 ; height 1 ; the carpus is always longer than the palm, 

 measuring 0.8 of the whole chela ; the meropodite is 3.3 times longer
