narrowing to the distal extremity, and the propoda having two 

 curved spines upon the inner distal angle, against which the 

 dactyla impinge. Posterior pair of pleopoda not longer than the 

 preceding, having the external ramus tipped with hooks.

This dt'soiiption is taken from Templeton's figiu'c, Avhich is not w'ell 

 drawn. There is nothing, either in it or his description, that war- 

 rants its being considered a distinct genus ; and there is likewise 

 nothing, as regards the drawing, that precludes it from belonging to 

 the genus AmphWwe. If the telson (which is neither figured nor 

 dcsciibcd) should be found to be formed into a hook, then it belongs 

 to SunamjphWioe ; but this not being shown, it is better to retain it 

 in the genus AmpMihoe, of which it appears to be a young animal.

" Body rather stout. Coxae broad. Superior antennae longer than 

 half the body, second joint much the longest; flageUum nearly 

 twice as long as the base, having about fourteen articuli, articuli 

 long, setDe very few and short. Inferior antennae shorter than the 

 superior, base much longer than the base of the superior ; last joint 

 longest, and about as long as the flageUum. First pair of guathopoda 

 small, oblong, narrow, narrower at apex. Second pair* of gnatho- 

 poda stout, broad, subrectangidar, transverse at apex, the palm 

 being apical, little excavate, and unevenly so ; inferior angle pro- 

 minent and acute ; dactylos moderately large. First and second 

 pairs of pereiopoda quite short, foiulh and fiilh subequal, thii-d 

 much shorter ; setae very few, rather short ; basa a little broad, 

 proportionably broadest in the fifth pair.

 closely appressed, and but little shorter than the articuli, others di-
