82 SMITHSONIyVN MISCELLANEOUS COLLECTIONS 



122. CHARYBDIS GRANULATA ' De Haan 



Charybdis granulata De Haan, Fauna Japonica, Crust., p. 42, pi. i, fig. i. 



Colors in life : Pubescence of upper surface brownish ; some white 

 spots among" the warts or granules, which are bright red. Below 

 bluish, mottled with white and pale red. 



Dimensions of a male : Length of carapax, 2.36 ; breadth, 3.4 

 inches. 



Dredged in 10 fathoms, shelly mud, in the channels of Hongkong 

 Harbor. 



123. CHARYBDIS MILES De Haan 



Clwrybdis miles Dfi Haan, Fauna Japonica, Crust., p. 41, pi. xi, fig. i. 



A single specimen only was collected, a female, the dimensions of 

 which are: Length of carapax, 1.65; breadth, 2.27 inches; propor- 

 tion, 1 : 1.37. It is thus a little narrower than those measured by 

 De Haan, in which the proportion stands i : 1.445. 



Taken at Hongkong, China, a point at which the Portunidse seem 

 to reach their maximum development in size and in numbers, both 

 of species and individuals. 



124. CHARYBDIS TRUNCATA (Fabricius) Stimpson 



Portunus truncatus Fabricius, Suppl., p. 365. 



Thalamita truncata Milne Fdwards, Hist. Nat. des Crust., i, 463. De 



Haan, Fauna Japonica, Crust., p. 43, pi. 11. fig. 3, pi. xii, fig. 3." 

 Charybdis truncata Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. 39 [2,7], 



1858. 



This species seems to have much more affinity with Charybdis 

 than with the genus Thalamita, to which it is referred by De Haan. 

 Among the very numerous specimens in our collection there are 

 none so large (two inches in breadth) as those mentioned by Milne 

 Edwards. And the description of this latter zoologist applies by no 

 means as well to our specimens as do the figures and description of 

 De Haan. 



Colors in life : Carapax above dirty greenish ; feet with transverse 

 bars or patches of reddish-brown ; below white. 



Very common in Hongkong Harbor. 



^Charybdis natator (Herbst). 



'In pi. XII, fig. 3, of de Haan the male is the true truncatus of Fabricius; 

 the female is C. subornata Ortmann.
