There are two specimeus of this species ia the National Museum, col- 

 lected by Dr. Whitehurst at Garden Key, Tortugas, Fla. (No. 2052, U. 

 S.N.M.). They are a male and a female; the latter is the larger and 

 is 21.3 cm. long. The dactyli of the raptorial claws of the male have 

 six very long teeth. The female, on the contrary, has but three very 

 short lateral teeth in addition to the long terminal one. 



LYSIOSQUILLA MACULATA (Fabricius).

This species is represented by three specimens in the National Museum, 

 a male collected by Dr. William H. Jones, U. S. Navy, of the U. S. S. 

 Wachmett, at Tawhae, Marquesas, in 1884 (No. 6593, U.S.N.M.), and 

 a female collected by A. B. Steinberger at Samoa (No. 5148, U.S.N. 

 M.). The latter is 30 cm. in length and exhibits the same peculiarity of 

 the raptorial claws that Miers describes. Tlie dactylus has a stout ter- 

 minal tooth and seven or eight very small lateral teeth. The third 

 specimen (No. 3392, IJ.S.N.M.), also collected by Steinberger, is the 

 raptorial claw of a male from Samoa and exhibits ten well-developed 

 teeth (including the terminal one) on the dactylus. This is evidently a 

 true case of sexual dimorphism. 



LYSIOSQUILLA SCABRICAUDA (Lamarck). 



Squilla ficobricauda, Lamarck, Hist. Anim. sans Vert., v, p. 188, 1818. — Latreillr, 



Encycl. Meth. Hist. Nat., x, p. 470, 1825. 

 Squilla hoeveni, Herklots, Addit. Faun, carcin. Afric. Occident., p. 17, 1851. 

 Lysiosquillainornata, Dana, U. S. Expl. Exped., xm, Crust., i, p. 610, 1852. 

 Lysiosqnilla scabricauda, Miers, Ann. and Mag. Nat. Hist. (5), v, p. 7, 1880. 



There are two specimens, a female and a young male, in the Museum, 

 collected by Henry Hemphill at Johns Pass, Fla. (No. 6471, U.S.N. 

 M.), one male specimen collected by D. S. Jordan at Key West, Fla. 

 (No. 14112, U.S.N. M.), a female from Galveston, Tex. (M. Wallace, 

 No. 2268, U.S.N.M.), and another from Peusacola, Fla. (Silas Stearns, 

 No. 5150, U.S.N.M.), and a male collected by James D. Dana at Eio de 

 Janeiro (No. 2115, U.S.N.M.). The dactyli of the raptorial claws seem 

 to be a httle smaller in the females than in the males, but there is 

 nothing like the difference seen in L. glahriuscula and L. maculata.
