CRUSTACEA OF FEANZ-JOSEr LAND. 103 



Laophonte perplexa, sp. B. (PI. 7. figs. 1-7.) 

 Several specimens of a Laophonte that appear to be undescribed 

 were obtained in a gathering of small Crustacea collected off 

 East Grlacier, Cape Flora, in 30 fathoms, on July 21sfc, 1897. Its 

 characters are somewhat intermediate between those of Laophonte 

 curticauda and Laophonte similis. It is rather smaller than 

 either of these species, being only about '63 mm. {-^ of an inch) 

 in length. The body is in general appearance like that of 

 L. curticauda. The rostrum is short, and the antennules are 

 seven-jointed ; the fourth and fifth joints of the antennules 

 are shorter than the others, as shown by the formula, which 

 indicates approximately the proportional lengths of all the 

 joints : — 



Proportional lengths of the joints 14 . 20 . 16 . 5 . 3 . 7 . 11 



Numbers of the joints 1 2 3 4 5 6 7* 



The posterior foot-jaws (fig. 3) resemble very closely those of 

 L. similis except that the terminal claw is somewhat strono-er. 

 The first pair of swimming-feet (fig. 4) are intermediate in 

 structure between those of L. similis and L. thoracica ; the outer 

 branches are short and two-jointed, the last joint being about 

 twice the length of the first, the terminal claws of the inner 

 branches are moderately stout. The fourth pair (fig. 5) have 

 the outer branches elongate and slender, and the inner branches 

 short and composed of two subequal joints. The fifth pair 

 (fig. 6) are nearly like those of L. curticauda, but the secondary 

 joints are proportionally rather smaller, and the armature of 

 both joints is somewhat different. The caudal furca (fig. 7) 

 resemble those of L. similis, being rather longer than the last 

 abdominal segment. 



Remarks. The Laophonte referred to above is one of those 

 perplexing forms, met with now and again, which are somewhat 

 difiicult to dispose of satisfactorily. Its characters are such 

 that it might be considered a variety of Laophonte curticauda 

 as well as of L. similis ; in these circumstances it appeared to me 

 to be better to give the form a distinct name.
