mass of minute mosaic-work ; under the magnifying glass it 

 has the appearance of the stomach-lining of some herbivorous 

 animals. 



This part, so spined and configured, is very distinctly divided 

 from the rest of the lower surface, its margins being verj' 

 abruptly and strongly defined. The remainder of the epi- 

 dermis of the fish is perfectly free from spines, either exposed 

 or hidden, except a patch covering the greater part of the 

 interorbital space and fore part of the back, extending from 

 thence towards the dorsal for a short distance in a triangular 

 shape (the apex pointing rearward), and thence in a single row, 

 ending near the dorsal with a slight widening in the pattern. 

 These spines are small, weak, short, and exposed, very much 

 smaller and finer than those on the belly, and with points 

 inclined backward. The nose, cheeks, sides, back, and re- 

 mainder of the under-surface are covered with skin smooth 

 as satin, on the back and sides resembling that of the elephant- 

 fish {Callorliynchus). 



The anterior radices of the dorsal and anal fins commence 

 in the same vertical plane, and posterior radices terminate in 

 the same relationship. They are both furnished with and rise 

 from a considerable muscular base, and are (with the caudal 

 fin) of very fleshy nature. They are of even altitude, and 

 agree in free altitude with the upper and lower free lobes of 

 the caudal fin. The pectoral fins the birds had destroyed. 

 The caudal fin is large and broad, margin much rounded. 

 The nostrils are formed by a low semi-spherical tubercle 

 partially sunk in a sulcus, with two apertures in each, the 

 anterior one rounded, the posterior one elongated. At the rear 

 of each sulcus is a crescent-shaped little trench the posterior 

 edge of which is creuulated. The nostrils are situated much 

 closer to the orbit than to end of snout. 



One eye was also destroyed by the birds ; the remaining 

 one had a silvery iris. The eye is comparatively large. The 

 orbits are partially encircled by an extension of the lateral 

 line, the lower limb of which extends along the cheeks well 

 on under them towards and round the end of the snout, the 

 upper limb running from the angle of divergence from the 

 lateral line directly upwards, and then partly along top of 

 head on each side, then down and between nostril and eye 

 till it meets lower line. Another branch of the line diverges 

 from that previously described, running down the sides of 

 cheeks, and one crosses the back of the head. The lateral 

 line itself runs in a wide angle from the first-described di- 

 vergence high up the side, having another small branch as 

 an offset from its lower side over origin of pectorals ; from 

 junction with this last small branch it curves still higher on 

 to back, then follows along upper side for some distance, then
