472 ACTAEA RUFOPUNCTATA. 



2. Actaea nodipes Heller. 



Heller, Sitziingsber. Wiener Akad. Bd. 43, pag. 329., 



Alpli. Milne Edwards, Nouv. Arcliiv. I, pag. 274. 



A very fine female specimen was collected at Djeddab , 

 entirely agreeing with the description , given by Heller. 

 Breadth of carapace 19 mm., length 13 mm. The upper 

 surface of the equally sized hands of the chelipedes are 

 provided with tubercular granulated prominences , the outer 

 and lower surfaces are ornamented with minute granules, 

 placed partially in longitudinal rows. 



3. Actaea rufopunctata M. Edw. 



A female Actaea , provided with eggs , was in the col- 

 lection , greatly resembling the above mentioned species ; 

 still I hesitate to call our specimen identical with it. Our 

 specimen entirely agrees with the description and the 

 figure of this species , given by Mr. Alph. Milne Edwards 

 (Nouv. Arch. t. I, pag. 268), but it is not of the described 

 size. In our specimen the carapace is only 14 mm. broad 

 and 9 mm. long , while the adult Actaea rufopunctata has a 

 size of 40 mm. The carapace is greatly enlarged , convex , 

 and its surface is divided by very large and deep grooves 

 anteriorly as well as posteriorly into a great number of 

 regions ; these grooves are covered with a dense pubescence , 

 the upper surface of the carapace being covered with some 

 scattered hairs. The several regions are covered with close 

 granules. The front is very deflexed, somewhat emarginate 

 in the middle , but for the rest little prominent. Protogastrical 

 regions divided by a longitudinal groove into two regions; 

 cardiacal region however scarcely provided with a trace of a 

 longitudinal groove. The antero-lateral margin is divided by 

 four incisions into five little prominent rounded lobes, the 

 anterior of which is the little prominent outer angle 

 of the orbit and flows almost together with the second 

 lobe. The legs agree entirely witli the quoted figure.
