Sub-Family II. Srsarmmx. 
Sesarmine, Dana, U.S. Explor. Exped. xiii, Crust. part i, p. 333, 
(1852). 
Internal antenne concealed by the front. Third joint of the 
external maxillipeds crossed by an oblique, usually piliferous, crest. 
(Body usually thick and convex). 
CYCLOGRAPSUS. 
Cyclograpsus, M. Edw. (part) Hist. Nat. Crust. ii, p. 77, (1837) ; 
Dana, U.S. Explor. Exped. xiii, Crust. part i, p. 359, (1852). 
Carapace flat above, curving slightly downward anteriorly. Front 
straight. Antero-lateral margins thin, entire. Eyes short. Third 
joimt of the external maxillipeds with the anterior margin truncate, or 
shghtly emarginate. Abdomen of the male scarcely narrower at base 
than the adjacent part of the sternum. 
The animal is smooth, entirely destitute of spines and tubercles, or 
hairs, except on the tarsi of the ambulatory legs. 
The three species of Cyclograpsus figured by MM. Jacquinot and 
Lucas on plate vi of the Atlas of the Voyage au Pole Sud do not 
really belong to this genus. 
44. Cyclograpsus lavauxi.* 
Cyclograpsus audouinii, Dana, U.S. Explor. Exped. xii, Crust. part 
1, p. 359, pl. xxi, fig. 2, (1852), nec Edwards. 
Cyclograpsus Lavauxi, M. Edw. Ann. Sci. Nat. xx, p. 197, (1853). 
Cyclograpsus white, M. Edw. Ann. Sci. Nat. xx, p. 197, (1853). 
Very near the C. Audowinii, but with the tarsi longer and 
more slender. Carapace and legs nearly smooth, with marbled spots, 
(M. E.). 
New Zealand (Coll. Paris, Brit. Mus.). 
The C. whitei is said to differ from C. lavauai only in the 
somewhat wider carapace, and in the form of the third joint of 
the external maxillipeds, which is rather longer and less dilated 

* Under the name of Gnathochasmus barbatus, Macleay, White has united 
this species and C. punctatus, M. Edw. from the Cape of Good Hope (List. 
Crust. Brit. Mus. p. 40, 1847).
