The form is iiioderatel)- elono;ated, the height o\-er the anus beiiiij' S' _> — 10' ^ times (in \-()un<^- 

 individuals sometimes ahnost 12) in the total length. As in other Lvcodes species the head is some- 

 what depressed, whilst the somewhat compressed trunk passes e\enh- into the strongh- compressed 

 tail. The head is a little broader than the trunk; its greatest thickne.ss lies over the cheeks and is 

 ca. I' lo-i'^u greater than the greatest height of the trunk. In adult .specimens the anus lies almost 

 at the middle of the body, as its distance from the snout is 47,8—49,3",, of the total length; younger 

 specimens (under 120 mm.) ha\e relatively longer tails, the distance of the anus from the snout in 

 them being 43,1— 47^0 of the total length. 



The head is relatively .small, its length being only 22,4-25,3",, of the total length. The eyes 

 are situated high up, so that their upper margins project forward over the forehead, and the space 

 between them is somewhat hollow; their longitudinal diameter (in specimens of 118-223 mm.) is 

 6 — 6,9 times in the length of the head or 4 3,6";, of the total length: they are thus relatively small. 

 The length of the snout, reckoned to the eye, is 2,9—3,7 times in the length of the head or 7,6— 8,6 "V, 

 of the total length. The upper-jaw extends to the vertical line through the middle of the eye; the 

 end of the snout projects a certain distance in front of the underjaw. The lips are thick; the under- 

 lip has a dependant fold on each side, and the fold of skin along the underjaw's lower edge is over- 

 lapping on the chin. The tube-shaped nostrils are well-developed. Along the upper and under-jaws 

 are shallow pits for the lateral line. The strong teeth are placed in a single row on the inter- 

 maxillaries (10 15), on the palatals (9—14) and on the mandible (10 — 151 ; on the foremost part of 

 the jaws (especially on the under-jaw) the>- form however a double row; further, there is a small gron]i 

 (4 — 5) on the portion of the vomer Ijing between the anterior ends of the palatals. 



The dorsal fin begins at a distance from the .snout equal to 30—31,7",, of the total length; 

 it contains 91—96 rays, the anal 71 — 76. The ventral fins are small (of a lengtli almost equal to the 

 breadth of the forehead between the eyes). The length of the pectorals is 13,1 — 13,6 '\, of the total 

 length, i. e. almost equal to the distance between the posterior margin of the eye and the edg^e of 

 the o-ill-cover; thev contain most frequently 18 — 19, more rarely 17 or 20 ray.s, of which the lower ones 

 project at their points beyond the covering skin. 



The scales in the larger .specimens (163—223 mm.. Tab. \'II, fig. i f & g) cover the sides of 

 the tail almost completely, but on its foremost part are already .somewhat di.stant from the dorsal fin 

 and continue forward from thence on the side of the trunk as a broad wedge, ending a little behind.
