"ENDEAVOUR" SCIENTIFIC RESULTS. 



In one specimen which I imagine to be a mature male, 

 the first gnathopod (Fig-. 11 a) is long- and slender and 

 bears dense tnfts of long slender setae on the ischium, 

 mems and carpus; the second gnathopod (Fig. 11 ft) is 

 practically as drawn by Stebbing, propod only very slightly 

 expanded distally. basis not expanded. 



Fi;j. 11 ,,,. Lembo.< i>lnliti-anthus (Stebbing). 

 First gnathopod of male. 



In the female (Fig. 11 r) and in the immature males 

 appendages are not so elongated and correspond more 

 nearly to the figures given by Stebbing of the "Challenger" 

 specimens (1888, pi. 110). ' 



It will be seen from the figure of the adult male (Fig. 

 11 a) that in this character L. philacanthus presents very 

 considerable resemblance to L. longipes (Liljeborg) and 

 L. web'ster i (Spence Bate) from the Northern Hemisphere. 

 In these species, however, the arrangement of the long 

 slender setae on the first gnathopod is slightly different. 



In 1914 Stebbing redescribed L. fueyiensis (Dana) from 

 specimens obtained from the Falkland Islands and 

 identified with that species the form from the Indian Ocean 

 described under the name of L. kergueleni by Walker in 

 1909. From the description and figures given by Stebbing 

 it is evident that L. fuegiensis approaches very closely to 

 L. phil(ic<ntthtis, but as yet the fully developed male does 

 not appear to have been described.
