length exclusive of the caudal fin. The lateral line extends nearly 

 in a straight line from the branchial cleft to the end of the root 

 of the tail; it is merely marked as a furrow with indistinct pits 

 along its course; in the larger specimen at its cephalic end two 

 slight furrows run parallel with it above and beneath. The head 

 is moderate, rather large, its length is contained about 5 times in 

 the total exclusive of the caudal fin; the snout is short, nearly 

 equal to the transverse diameter of the eye, its anterior contour 

 is rounded; there is a slight median gibbosity in front over the 

 mouth. This is moderate, its aperture hardly reaching the ver- 

 tical from the anterior margin of the eye. Nostrils in front and 

 a little above the eye, the posterior aperture largest and oval; 

 Eye moderate; behind it, extending towards the nape and down- 

 wards along the preoperculum, are two series of conspicuous pores. 

 The space between the eyes is nearly flat and rather broader than 

 the diameter of the eye; behind, the nape rises convex, presenting 

 a median furrow in front of the first dorsal in the older specimen. 

 On the nape, in the larger specimen, are a number of very dis- 

 tinct hyaline cylindrical warts, just like those of Bellottia except 

 in shape; the latter have been described by Professor Emery (1) 

 and are nearly hemispherical. In Eretmophorus they begin just 

 behind the interocular space and appear to form a double series; 

 in the older specimen I counted eight, but a few more extend 

 towards the head of the lateral line ; they are evidently sertse- 

 organs allied to those of the lateral line. In concluding I must 

 state that these warts are not to be seen on the two younger 

 specimens, in which they appear to be represented by pores, more 

 numerous and more distinct than in the older and larger specimen. 

 The gill-openings are rather wide, the branchiostegal mem- 

 branes .are largely developed, with robust rays; the opercular 

 bones are smooth and very thin ; the branchial cavities contain 

 four complete arches. The specimens are so very fragile that I 

 did not dare to pursue my investigations further. 



, The Jins are those of an Anacanthine fish, but I could not 

 see any transverse articulations in the first ray of the first dorsal ;
