534 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



Lower jaw slightly shorter. No teeth on vomer and palatines. Tongue voluminous, 

 smooth, with a band of singular spheroidal papillae down its middle. Cleft of the mouth 

 extending to vertical of hind margin of eye. No pores. Branchial apertures wide; small 

 pseudobranchiae. Gill-rakers spiny, stout, in double series on the anterior arch. Branchi- 

 ostegal membranes free from the isthmus. 



Barbel slender, longer than the transverse diameter of the eye. Preoperculum with 

 hinder margin nearly straight, rounded below and very slightly crenulated. 



The first dorsal fin commences exactly above the insertion of the pectorals; its first 

 spine is very short, the second ray very robust, longest, regularly serrated in its front up 

 to its extremity, which is prolonged in a filament; its length is equal to the distance of 

 the dorsal from the eye. The second dorsal commences above the sixth anal ray; its rays 

 are very low, especially in the first third of its length. The anal commences immediately 

 behind the anal aperture, it is at least five times as high as the second dorsal, it gradually 

 becomes lower toward the end of the caudal region, where it is nearly subequal to the end 

 of the second dorsal, but always higher. I can make out in my specimens a caudal, con- 

 tinuous with the dorsal and anal, but distinguished by its longer rays. The pectorals are 

 in a bad condition in both specimens, but the upper ray appears to be slightly elongated. 

 The veutrals are inserted below the pectorals, but distinctly in advance; their outer ray 

 is filamentous, stouter, and greatly prolonged, reaching to the twentieth anal ray. 



Budial formula: I D. |; II D. 110 circa; A. 120 circa; C. 3; P. 20; V. j ; Br. VI. 



I may add that I have taken extra care in making out the radial formula, which is not 

 an easy undertaking in fishes of this sort. Except the second dorsal and anal in which 

 the given number of the rays is approximated, I am quite certain about the rest. 



Chalinura mediterranea is evidently allied to C. Simula, Goode and Bean, and to C. 

 leptolepis (Giinth.), but has a shorter and more carina tc snout thau either. In this it 

 approaches more O.femandeziana (Giinth.), whilst its veutrals witli a larger number of rays 

 bring it near C. Murrayi (Giinth.). But it is withal sufficiently different to warrant its 

 specific distinction. I have to thank my friend. Prof. G. Brown Goode, for having specially 

 railed my attention as to the Letter determination of these two specimens, which I had left 

 up to the present under the name (with query) of Goryphcenoides serratus (Lowe),* a species 

 which must be canceled from the "Systema Piscium." 



I had been hitherto under the impression that Krohnius filamentosus, Cocco, might be 

 the larval form of the fish I have now named Chalinura mediterranea; but a careful exam- 

 ination has now shown me that that singular larval form, evidently a Macrurid, although 

 possessing the shape and some of the indications of characters pertaining to Chalinura,h&s 

 a smooth second ray in its first dorsal. The doubt must yet remain, for I do not think it 

 likely that it should prove to be the larva of my Hymenocephalus italicus.

Trachyrhynchus scabrus. Capello has observed several specimens in the markets of 

 Lisbon and at Setubal (Peixes de Portugal, 1880, 32).
