along inner margin; outermost process with frilled membrane along 

 outer margin. 



Female maxilliped (fig. 146) 2-segmented, situated posterior and 

 medial to maxilla base, on ovoid, padlike projection. First seg- 

 ment strongly developed, irregular, narrow proximally, broad medially, 

 with 2 sub triangular projections from inner sm-face. Second segment 

 and terminal process clawlike, segment short, distinct from terminal 

 process, with setule-like accessory process from distal inner siu-face. 

 Male maxilliped (fig. 14c) similar to that of female except with addi- 

 tional, loioblike projection on proximal inner sm^face of first segment. 

 Female sternal furca (fig.l4(/) V-shaped, tines bluntly pointed. Male 

 sternal fiu^ca (fig. 14e) with V-shaped sinus but lateral margins almost 

 parallel, tines not diverging as in female. 



For nature of thoracic legs and armatm'e, see figiu-e 15 and table 7. 

 Flabby, bifurcate projection present just posterior to interpodal plate 

 of first thoracic leg, similar though less distinct projection present 

 posterior to second thoracic legs. 



♦Numerous hairlike projections (s) in middle of segment, not Included in table, 

 t Roughened area (in this case by denticulations) . 



Discussion. — The synonymyzing of Euryjphorus coryphaenae Kr0yer 

 with E. nympha Steenstrup and Liitken was first done by Bassett- 

 Smith (1899) although no reasons were given. Wilson (1913) sug- 

 gested that the two were synonymous but it was not until Shiino 

 (1954b) that Bassett-Smith's belief was reiterated. Shiino did not 

 have Kr0yer's original description of E. coryphaenae so did not give 

 an analysis of the two species. 



In a comparison of E. nympha and E. coryphaenae, the major differ- 

 ences appear, from the publications, to be in the sternal furca (that of 

 E. nympha having more widely spaced tines) and in the armature and 

 its position on the first thoracic leg (E. coryphaenae figured as having
