The form is moderately elongated, the height over the anus being 8 1 to times (in young 

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

 what depressed, whilst the somewhat compressed trunk passes evenly into the strongly compres 

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

 ca. i 1 io i-',, 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 47,8 411,3 ",. of the total length; younger 

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

 them being 43,1 -47% 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 nun. 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 01 7,6 8,6 

 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 oxer- 

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

 the jaws (especially on the under-jaw) thev form however a double row; further, there is a small group 

 (4 5) on the portion of the vomer lying 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 length almost equal to the 

 breadth of the forehead between the eyes). The length of the pectorals is [3,1 — 13,6° oi the total 

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

 the gill-cover; they contain most frequently 18—19, more rarely 17 or 20 rays, of which the lower ones 

 project at their points beyond the covering skin. 



The scales in the larger specimens (103—223 nun., Tab. VII, fig. 1 f nV g) cover the sides oi 

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

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