NO. 1659. AMERTCA7C SPECIE f^ OF 8YNALPHEVS—C0VTIERE. 



T3 



slender, 5.5 times longer than wide; (3) the fingers of the small chela 

 are elongated, the i)roportions being: Fingers 1; total length 2.38; 

 height 0.76 ; proportion L. : H : = 3.12 : 1 ; the carpus is 0.5 of the total 

 length; the large chela is absent; the second and third pairs have 

 their usual characters. 



This specimen may be distinguished under the name of S. hrooksi 

 streps-iceros. 



The elongation of the carpocerite in this specimen is a variation in 

 the direction of the species hemcki. 



A second variation, bearing this time on the small chela, charac- 

 terizes some specimens from the Bahamas (3 females, 5 males) ; the 

 carpocerite remains short (proportion 4, 4.1), thicker even than in 

 typical S. hrool'sl; the spines of the scaphocerite and of the carpo- 

 cerite, especially of the latter, are stronger and longer than in the 

 tj^pes; the large chela is similar in the two sexes, and even slightly 

 thicker in the females; the proportions are those of the extreme 

 cases met in S. hroohsi. 



The palm is thus shorter, while remaining as broad, in this char- 

 acter approaching S. hervichi ; the proportions of the small chela 

 are : Female, fingers 1 ; total length 2.45 ; height 0.85 ; carpus 0.53 of 

 the total length ; male, fingers 1 ; total length 2.5 ; height 1 ; carpus 

 0.57 of the total length ; the meropodite is 3.85 times as long as wide 

 in the females, 3.8 times in the males. The males thus seem to 

 show particularly the tendency to the lengthening of the carpus 

 which characterizes S. herricM^ but this lengthening is almost as 

 marked in the females, where it is hidden by the elongation of the 

 ciiela and especially of the fingers; the feet of the second and third 

 pairs are those of S. hvool'si. 



Tliese specimens may be named S. hrooksi eleutheroe.
