534 DEEP-SEA FISHES OK THE ATLANTIC BASIN. 



Lower jaw slightly shorter. No teeth on vomer and palatiues. Tongue voluniinous, 

 smooth, with a band of singular spheroidal papilla^ down its nii<ldle. Cleft of the mouth 

 <^xtending to vertical of hind margin of eye. No pores. Branchial apertures wide; small 

 ])seudobranchia'. Gill-rakers spiny, stout, in double .series on the anterior arch. Braiichi- 

 ostegal menibraues free from the isthmus. 



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

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



The Urst dorsal tin commences exactly above the insertion of the pectorals; its lirst 

 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 fi'om the eye. Tlie second dorsal commences above the sixth anal ray; its rays 

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

 behind the anal aperture, it is at least live 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 upi>er ray appears to be slightly elongated. 

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

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



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



1 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 secimd dorsal and anal in which 

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



Vlidliinna medUerraned is evidently allied to C. simiila, Goode and Bean, and to G. 

 Jeptolepis (Giinth.), but has a shorter and more cariuate snout than cither. In this it 

 aijproaches more C. fernandeziana {Gvmth.), whilst its ventrals with a larger number of rays 

 bring it near C. Murrai/i (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 

 called my attention as to the better determination of these two specimens, which I had left 

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

 which must be canceled from the "Systema Pisciuin." 



I had been hitherto under the impression that Krohnius Jilamentosus, Oocco, might be 

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

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

 possessing the shape and some of the indications of characters pertaining to Chulinura,\vAii 

 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 Hymenoccphalus italicus.
