8-] milliin. long (exclusive of the basal portion of tlie abdomen). 

 The pterygostomian regions are sulcate in this species. 



Actcea areolata has previously been recorded from the Sooloo 

 Sea or Balabac Straits.

Xantho rufopunctatus, Milne-Edwards, Hist. Nat. des Crustaces, t. i. 

 p. 389. 



Actaea rufopunctata, Alph. Milne- Edwards, Nouv. Arch, du Mus4um 

 Hist. Nat. t. i. p. 268, pi. xviii. fig. 1. 



Actaea pilosa, Stimpson, I. c, p. 31, and A. Milne-Edwards, I. c. 

 p. 265. 



Six fine specimens (three S , three 2 ) are in the Collection, 

 four of which were collected at King Island Bay, while the two 

 other male specimens were found at EJphiustone Island. 



The cephalothorax of an ova-bearing female is 28 millim. 

 broad and 20| millim. long. These numbers in an adult male 

 are respectively 32 millim. and 23 millim. 



I refer these specimens to the common Indian Actaea rufo- 

 punctata, as they nearly completely present the striking charac- 

 ters of that species. In all these specimens, however, the whole 

 upper surface of the cephalothorax and the outer surface of the 

 legs, besides being clothed with a short close down, similar 

 to that of A. tomentosa, are moreover covered with longer 

 yellowish-brown hairs, which were not described by the French 

 carcinologist ; and, secondly, the cardiac region of the upper 

 surface of the cephalothorax never shows even a trace of a 

 median groove, which is visible in Milne-Edwards 's figure. 



The specimens are of a yellowish colour, and marked with red 

 spots on the carapace and on the legs. The individuals which I 

 described some time ago under the name of A. rufopunctata 

 (Notes from the Leyden Museum, vol. ii. p. 172, and vol. iii. 

 p. 96) seem to belong to the same species, but the median frontal 

 lobes are less prominent in the Eed-Sea specimens, a difference 

 which may probably be ascribed to their being younger. Never- 

 theless, the small size of these specimens, already bearing eggs, 

 is very remarkable. 



Actcea pilosa, Stimpson, from Hongkong is, in ray opinion, 

 identical with A. rufopunctata. As regards Actcea Kraussi, 

 Heller, from the Eed Sea and from the Island of Bourbon, I may 

 observe that it differs from these specimens by its compara- 

 tively more enlarged cephalothorax, by the subhepatic regions
