96 ACTAEA HELLERI. 



Actaea hirsutissima Rupp. 



Two male specimens and an adult female with eggs are 

 in the collection : the male specimens having the carapace 

 22 mm. broad, the adult female only 18 mm. 



Actaea r ufo punctata M. Edw. 



The three specimens are again of the same small size 

 as that, which I described in my former Note on the Djed- 

 dah Crustaceans (Notes of the Leyden Museum, Vol, II, 

 pag. 172), the largest male specimen having the carapace 

 only 14 mm. broad. The grooves between the regions are 

 covered with a dense pubescence, and the whole surface 

 of the carapace is covered with tolerably long hairs. — 

 I therefore still doubt whether these specimens really belong 

 to the true rufopunctata Edw.

Three fine specimens (2cf , 19) of this very rare species , 

 the habitat of which was still unknown, were collected 

 on the shores of the harbour of Mecca. — Carapace en- 

 larged , convex in all directions , regularly curved anteriorly. 

 Regions bordered by tolerably broad but shallow grooves and , 

 like the nearly entire, undivided, finely curved anterola- 

 teral margins, provided with numerous, conical, acute 

 small tubercles, that are less prominent and more granu- 

 lar on the cardiacal and intestinal regions ; the few concave , 

 nearly straight posterolateral margins being more minutely 

 granulated. Front very deflexed and prominent, scarcely emar- 

 ginate neither in the middle nor at the sides. Under surface 

 of the carapace minutely granulated near the anterolateral 

 margins , but the outer surface of the externall maxillipeds , 

 of the sternal plate and of the terminal joint of the male abdo-
