616 " THETIS " SCIENTIFIC RESULTS. 



Six genera of this family are defined in " Das Tierreicli," to 

 ■which should have been added Paragruhia, Chevreux, 1901, as^ 

 mentioned in the appendix. 



Genus AMPITHOE, Leach. 



AmpithUe, Leach, Edinb. Encycl., vii., 1813, pp. 403, 432. 

 Ampithoe, Stabbing, Das Tieireich, xxi., 1906, pp. 631, 738. 



AMPITHOE FLINDERSI, Stebhing. 



Station 57. 



Amphithoe Jlindersi, Stebbing, Chall. Rep., Zool., xxix., 1888, p. 



1120, pi. cxviii. 

 Ampithoe Jlindersi, Stebbing, Das Tierreich, xxi., 1906, p. 635, 

 fig. 108. 



For this small species the collection did not supply the missing 

 information in regard to the antennae. The second gnathopods 

 differ from those of the specimen originally described by having 

 an excavation of the palm at right angles to the hind margin of 

 the sixth joint, probably indicative of male maturity. 



Locality. — Oflf Wata Mooli, 54 to 59 fathoms. 



Family COROPHIID^. 



Corophidce, Dana, Amer. Journ. Sci., (2), viii., 1849, p. 139. 

 Corophiidce, Stebbing, Chall. Rep., Zool., xxix., 1888, p. 1154.

To the eleven genera of this family defined in " Das Tierreich," 

 the genus Grandidierella, Coutiere, 1904, was added by name in 

 the appendix, and in the present report the genus Dryopoides is 

 transferred from the Aoridae to this family. Recently a second 

 species of Grandidierella has been described by myself, three new 

 species of Corophium have been described by Chevreux, and 

 Stimpson's species Corojyhiuin spinicorne ^nd Corophium salmonis 

 have had much needed light thrown upon them by J. C. Bradley, 



Genus CERAPUS, Say. 



Cerapus, Say, Journ. Acad. Nat. Sci. Phil., xi., 1817, p. 49. 

 Gerapus, Stebbing, Das Tierreich, xxi., 1906, pp. 665, 740.
