X 2. a little in front of the origin of the lateral line. Further, there is a number of fine lateral line pores on the top of the head, the operculum and preoperculum. The dorsal fin begins relatively far forward, namely, at a distance from the snout which is equal to 21,6" „ of the total length; it contains ca. 92 rays, the anal fin ca. 76 rays (half the tail fin being reckoned with each). The ventral fins are relatively long (3,5 , but ver\- thin. The pectorals are 8,5 mm. long and contain 15 rays, the lowermost of which extend at their points beyond the covering skin. The scales already show a tolerabl\- wide distribution, namely, forward to the tip of the pectoral fin when laid backwards. They are not \et ver\- close together, here and there also are some naked spots, especialh- on tlie hindmost portion of the tail, and in front the scah' covering projects forwards in the shape of a wedge leaving the belly and back bare. Further, the scales show signs of going to .spread out on to the unpaired fins. The lateral line seems to be mediolateral. It begins over the upper notch of the gill-cover, forms a slight arch over the flap of the latter, and can then be followed along the median line of the trunk as far as the vertical line through the anus; the pores are tolerabh" distant from one another and onl\ number 21 on the whole distance mentioned. Possiblv there is likewise a ventral branch, as on the one side there seem to be 2—3 pores on the bell\- in front of the anus. Tlie colour is a uniform brownish \ellow without any signs of stripes. The bellv shows blue-black owing to the peritoneum shining through. In the journal of the Expedition it is written.
