having seven instead of six anal finlets and higher anterior dorsal 

 spines. 



Family LEPTOSCOPID^. 

 Genus Crapatalus Giinther. 



Crapaialus Giinther, Ann. Mag. Nat. Hist., (3), vii., 1861, p.86. 



According to Giinther's definition of this genus, there are no 

 teeth on the palate, and the cleft of the mouth approaches the 

 vertical line. Mr. C. Tate Regan has very kindly re-examined 

 the type of C. novce-zelandice for me, however, and informs me 

 that both the vomer and palatine bear teeth, and that when the 

 head is in position and the mouth closed, the cleft of the latter 

 is not nearly vertical.

 Head, to end of opercular lobe, 3*5 in the length from the tip of 

 the lower jaw to the hypural; depth at vent 7-4 in the same, and 

 2*1 in the head. Eye equal to the interorbital space, and about 

 as long as its distance from the tip of the upper jaw, 7 in the 

 head. Depth of caudal peduncle a little greater than the eye, 

 5*2 in the head. Seventh dorsal ray equal to that of the anal, 

 3*3 in the head. Longest pectoral ray 1*1, fourth ventral ray 

 2-3, and caudal fin 19 in the head. 



Body elongate, head and shoulders depressed, the remainder 

 compressed. Head entirely naked. Body covered with large 

 cycloid scales extending forward to above the operculum on the 

 back, and to behind the pectoral and ventral fins on the lower 

 surface; they are smallest in front of the dorsal fin, and encroach 

 on the bases of the caudal rays. Lateral line almost straight 

 from the suprascapular along the middle of the body to the base 

 of the caudal. Breast armed with two small spines anteriorly 

 which project forward. Urinogenital apertures immediately in 

 front of the origin of the anal fin, with a mitiute papilla pro- 

 tected by an overhanging sheath.
