44 Gr. O. Sars. 



curved, anterior extremity very broad and blunted, posterior 

 narrower and rounded: — seen from above oval, greatest width 

 not attaining to 2/3 of the length, both extremities obtusely 

 pointed. Surface of shell smooth and polished. Rostral ex- 

 pansion in female much produced and, when seen laterally, grad- 

 ually tapering to an acute point, seen in front, narrow lingui- 

 form, Avith a distinct notch on each side of the obtusely 

 rounded tip; that in male transversely truncated at the end, 

 lateral keels projecting beyond the apical face. Legs 12 pairs 

 in female, 10 pairs in male; 1st pair in the latter with the 

 hand rounded and carrying about 7 sharp spines along the 

 palmar edge, subapical lobe rather elongated but narrower than 

 in the preceding species. Colour in alcoholic specimens whitish. 

 Length of adult female 2^/2 mm., of male about the same. 



Remarks. Though the description and figure given by 

 Brady is rather imperfect, I cannot doubt that the above- 

 characterised form is the same species. At first I believed it 

 to be merely the young of L. macleayana; but on examining the 

 animal closer, I found all the specimens to be, in fact, fully 

 adult, though not even attaining half the size of that species. 

 From L. macleayana the present form moreover differs by the 

 comparatively higher and more compressed shell, the rather 

 différent shape of the rostrum, and the structure of the 1st 

 pair of legs in the male. 



Description of the female. 



The shell of fully grown, ovigerous specimens does not 

 exceed a length of 2^/2 mm., and this species is accordingly 

 much smaller than any of the other known forms. 



Seen from the side (fig. 1), the shell appears almost 

 circular in outline, though being considerably higher in front 

 than posteriorly. The dorsal margin slopes rather steeply 

 from the most prominent point to the posterior extremity.
