ANTHRACOMARTI. 55 



tlie second segment also long, with the median area of its anterior border con- 

 siderably produced to fit into the correspondingly deep emargination of the first 

 triangular intercoxal sternal plate. Coxal area of prosoma about one-fourth 

 longer than wide. Leg of first pair apparently shorter than the carapace, which 

 is about as long as the trochanter, femur, patella and tibia of the fourth leg. 



Measurements in vim. — Total length 12; carapace almost 5, width of carapace 

 3 ; length of opisthosoma 7, width about 4 ; length of its last three segments about 

 5 ; of sternal area of opisthosoma nearly 10; width of coxal area of prosoma 3*5 ; 

 length of fourth leg almost 7. 



Coseley, near Dudley. 



Type and only known specimen of this aberrant species in the Collection of 

 Mr. Walter Egginton (No. 10). 



Geraphrynus angustus, sp. no v. 



Allied to the last but shorter ; body about two and a half times as long as 

 wide. Carapace about one-fourth longer than wide, median length equal to that of 

 the anterior eight terga of the opisthosoma, its posterior border evenly and widely 

 convex. Opisthosoma much less than twice as long as wide, its width about equal 

 to the last three tergal plates ; the first, second, third and fourth terga sinuously 

 curved round the convex border of the carapace; the median area of the first 

 obliterated, of the second very short; the anterior border of the fifth sinuous ; the 

 plate about half the length of the sixth, which is more than half that of the seventh ; 

 seventh and eighth subequal and each about three-quarters the length of the 

 ninth. 



Measurements in mm. — Total length 9*5 ; length of carapace 4, width 2*5; length 

 of opisthosoma 5*5, width 3-8 ; length of sternal area of opisthosoma 7'5. 



Coseley, near Dudley. 



A single specimen in Mr. Walter Egginton's Collection (No. 36, one half 

 labelled also 26). 



In addition to its greater width as compared to its length, a character in which 

 it serves in a measure to bridge over the interval between G. torpnlo and the more 

 normal species of Gerajjhrynus, this new species differs from G. torpedo in the 

 sinuous curvature of the anterior four terga of the opisthosoma.
