 laminfe, the laminie being farther apart. Color of Echeneis naucratcs.

This genus differs from Bcmora chiefly in the length of the sucking disk, 

 which has 21 to 27 lamina'; the soft dorsal and anal are proportionately 

 short. (A metathesis for rcmelujo, the delayer or hiuderer.) 



2f.05. REMILEGI.i AUSTRALIS (Bennett). 



D. XXVII-22 ; A. 21 to 23. The length of the disk is 2^ in the total, the 

 width of the body between the pectorals 5|. Caudal truncated; dorsal 

 and anal fins not continued to the caudal. Color brown. This species 

 has the general habit of E. rcmora, but may be readily distinguished from 

 all the others bj'^ the extraordinary size of the disk, which is elongate, 

 snbelliptical, obtusely rounded anteriorly and posteriorly, and formed by 

 27 pairs of lamimie; it extends backward beyond the vertical from the 

 tip of the ventrals, and its length is 2^ in the total. The spines with 

 which the single lamina are armed are less conspicuous than in the other 

 species, and do not offer the same resistance to the touch. There is a 

 large posterior portion of the disk which is not provided with laminfe, 

 but quite smooth. The width of the disk, taken between the extremities 

 of the bony lamin.T, is ^ of its length; the membranaceous margin is 

 bent upward. The head and the body below the disk are depressed, and 

 their height is 9^ in the total length, whilst the width between the pec- 

 torals is 5J in it. The body between the disk and the vertical fins is 

 quadrangular, tapering posteriorly. The upper jaw is subtruncated, and 

 overreached by the lower, which is much narrower; both are armed with a 

 broad band of villiform teeth, and with an outer series of larger ones on
