SeSARMA ANGUSTIPES'f 



Sesarma angustipes, Dana, U.S. Explor. Exped. xiii. Cr. i. p. 358, 

 pi. xxi). fig. 7 (J 852) ? ; Cunningham, Trans. Linn. Soc. Zool. xxvii. 

 p. 493 (1871); Smith, Trans. Conn. Ac. ii. p. 37 (1869); nee 

 Stimpson, Ann. Lye. Nat. Hist. New York, vii. p. ti6 (1858). 



To this species I refer, with considerable hesitation, a male 

 example collected at Rat Island, Monte Video, with Chasmognathus 

 fffanu/afns. It is certainly not identical with specimens received 

 from the Smithsonian Institution, from Florida and the Tortugas, 

 under the name of S. angustipes (probably so named by Dr. Stimp- 

 son); but it appears to agree more nearly in the distinctly granulated 

 carapace and hand and mobile finger of the anterior legs with Dana's 

 description than do these specimens. In these latter the hand and 

 fingers are nearly smooth, and the carapace is more convex toward 

 the antero-lateral angles. If the Floridan species be not the true 

 iS. angustipes, Dana, it may be designated i^. stimpsonii. 



Dana gives merely South America as the habitat of 5. angustipes. 

 Prof. S. I. Smith has pointed out that there can be little doubt 

 that Dana's specimens were collected at Rio de Janeiro ; a specimen 

 from this locality is also referred to this species by Dr. Cunningham, 

 which I have examined and find to be identical with the Monte- 

 Videan example. They come nearer to S. cinerea, Bosc (of which 

 the Museum also possesses specimens from the Smithsonian Insti- 

 tution, from Carolina), being only distinguished by the more convex 

 and distinctly granulated carapace and strongly granulated hands. 



Halicarcinus planatus. 



Cancer planatus, Fabr. Ent. Syst. ii. p. 446 (1793). 



Halicarcinus planatus. White, Ann. & Mag. Nat. Hist xviii. p. 178, 

 pi. ii. fig. 1 (1846); Cunningham, Trans. Linn. Soc. Zool. xxvii. 

 p. 492 (1871) ; Miers, Phil. Trans, clxviii. p. 201 (1879), ubi synon. 



This widely spread inhabitant of the Antarctic region is very 

 common in the Straits of Magellan, where its occurrence at many 

 localities was noted by Dr. Cunningham. Dr. Coppinger's specimens 

 were from Elizabeth Island, 6 fathoms, on a sandy bottom (two females); 

 Sandy Point, 9-10 fathoms (one female); Cockle Cove, 2-32 fathoms, 

 on a muddy bottom (one female) ; Trinidad Channel, 4 fathoms, on 

 a bottom of fine sand (one male and one young). 



Pinnixa transversalis. 



Pinnotheres transversalis, M.-Edw. & Lucas, in d'Orbigny's Voy. 

 Ame'r. merid. Cr. p. 23, pi. x. fig. 3 (1843); Gay, Hist, de Chile, 

 Zool. iii. Cr. p. 156 (1849) ; Cunningham, Trans.' Linn. Soc. Zool. 

 xxvii. p. 492 (1871)? 



Pinnixa transversalis, M.-Edw. Ann. Sci. Nat. ser. 3, Zool. p. 220 

 (185.3). 



A male of rather small size is in the collection from Coquimbo. 

 This example agrees exactly with the description of M.-Edw. and 

 Lucas in possessing small and tomentose chelipedes, a transverse
