it as in P. barbadensis ; the spines on the lower side longer, the first or proximal arising close to the base 

 of the median, which it almost touches, and from which it diverges at an acute angle. Genital operculum 

 in male small, its length about equal to that of the circular sternal area of the cephalothorax and much 

 less than that of the upperside of the femur of the chela. Sternal area of third abdominal somite 

 straight from side to side.

I have seen, in all, seven specimens of this species in the Godman and Salvin 

 collection. Three of these are adult males, one an adult ovigerous female, and the rest 

 about half or three-parts grown. The smallest measures about 8 mm. in length. 



3. Phrynus operculatus, sp. n. (Tab. X. figg. 8, 8 a-c, a .) 



Closely allied to P. parvulus, but darker in colour, there being no red upon the interocular area on the carapace, 



femur of the chela is subequal to the fourth, and longer than the fifth, and the first spine upon the lower 

 side of the hand is isolated from the base of the median spine and pointing in the same direction. Apart 

 from these distinguishing features, which are found in both sexes, the male of P. operculatus differs from 

 that of P. parvulus in the great size of the genital operculum, the length of which far exceeds that of the 

 circular sternal area of the cephalothorax, and is almost equal to the length of the femur of the chela. 

 Correlated with the enlargement of this plate the sternal area of the second somite shows almost a 

 semicircular curvature, and that of the third is also curved and encroaches upon the sternum of the 



fourth segment. 

 Total length 13 mm., width of carapace 9 ; length of genital operculum ( <$ ) 4, width 5*5. 



Hab. Guatemala (Sarg). 



An adult male and female in the Godman and Salvin collection.

Colour : carapace blackish, with yellow rim, yellowish radiating spots, and a bright yellow-red patch on the 

 inner side of each lateral ocular cluster ; abdomen variegated, femora of legs spotted. Carapace with 

 sparsely arranged coarse granules, the anterior border covering the subfrontal process, lightly emarginate, 

 median ocular tubercle less than its own diameter from the anterior border ; lateral ocular clusters about 

 equidistant from the median tubercle, from the anterior border, and from the lateral border at the 

 emargination above the base of the first leg. Chela with trochanter and femur spined as in P. parvulus ; 

 spines of tibia differing from those of the three foregoing species in that the second and sixth are much 

 shorter than the fourth, and less than half the length of the third and fifth respectively, the eighth spine 

 is even more reduced than in P. parvulus ; hand as in P. parvulus. Genital operculum rather large, its 

 length exceeding that of the sternal area of the cephalothorax ; sternal area of third abdominal somite 

 straight from side to side. 



Total length 14 mm., width of carapace 8*5; length of genital operculum 2*5.

and no yellow spots upon the femora of the legs. The anterior border of the carapace is almost straight, 





and the lateral ocular clusters are about equidistant from the anterior border, from the lateral border above 

 the base of the first leg, and from the median tubercle. The third spine upon the inferior edge of the
