DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 1G9 



The U. S, Fish Commission received the type from the schooner Gatherer, of Glouces- 

 ter, Capt. Briggs Gilpatrick, which had been taken from the stomach of a Ground-shark, 

 (tSomniosus brevipimiis), on the Grand Bank of JSTewfoundlaud. 



GIGLIOLIA, Goode and Bean, n. g. 



A genus of Nofncnnthida', distinguished from XofacantJi us by tlie less advanced position 

 of the dorsal, the first dorsal spine being placed in the vertical over the vent and close to 

 the vertical from the first anal spine. Dorsal spines 6-9; anal spines 15-18, these being 

 longer and more slender than in Notacanthus, enveloped nearly to their tips in a membrane, 

 and grading imperceptibly in length and size into those of the anal, which is co'^ paratively 

 high. The greatest height of the body is in the region of the ventral fins, am. che lateral 

 line, which is conspicuous, is arched over the pectorals and ventrals, but follows closely the 

 dorsal outline until it passes beyond the dorsal spines, after which it is directed in a straight 

 line to the tip of the pointed tail. Head comparatively broad, mouth inferior, almost suc- 

 torial, with lip absent in the middle portion of mouth in front; teeth in each intermaxillary 

 20-22; snout thick, swollen, much produced, nostrils large, conspicuous, covered by a mem- 

 branous flap. Pectoral short, broad, rounded. Ventrals placed low down and completely 

 united, extending to the vent. 



In general appearance and proportions this form resembles the high-backed division of 

 the genus Kotacanthus, to which belong ¥. nasus and N. GhemnitzU. Its mouth, however, 

 is placed more on the under surface of the head than even in N. scxapinis. 



This genus is named in honor of Commendatore Enrico Ilillyer Giglioli, professor in the 

 University of Florence, and founder of the Central Museum of ItallauVertebrates, who has 

 been a leader in all the eflbrts of tlie Italian Government in deep-sea research, and whose 

 thorough works upon the geographical distribution of Italian vertebrates, both terrestrial 

 and aquatic, are of an importance which can not be overvalued. 



Th(^ only species assigned to this genus is that obtained by the Challenger off the south- 

 west coast of South America, and referred by Giinther to Notacanthus Bonapartii. This 

 form, represented by a single individual 11 J inches long, from a depth of 400 fathoms at 

 station 310, we propose to designate by the specific name Mosckyi, in memory of the late 

 lamented Henry Nottidge Moseley, F. k. s., who was naturalist of the Challenger, and Linacre 

 professor in the University of Oxford.

The following excellent description is that written by Dr. Giinther: 



Body moderately elongate, its greatest depth opposite the ventral fin and contained 

 2§ times in distance of the vent from the end of the snout; the length of the compressed 

 oblong head is contained 2J times in the same length. The snout is thick, swollen, much 

 produced beyond the narrow transverse mouth, which is opposite to the front margin of 

 the orbit, and quite at the lower side of the head. Twenty teeth on each side of the upper 

 jaw. The eye is close to the ui)per profile, two-thirds of the length of the snout, one-fifth of 

 that of the head, and less than the width of the interorbital space. Gill-openings of mod- 

 erate width, the gill-mcnibranes being confluent in the vertical from the ujiper end of the 

 gill-opening, and not attached to the isthmus. 



The whole body and head are covered with minute, smooth, imbricate, and adherent 

 scales. 



All the dorsal spines are short, the anterior very short, the second opposite to the vent. 

 The anal spines commence imniodiately behind the vent, and increase in length posteriorly, 

 l^assing into the flexible rays, which are of varying and indefinite number. The pectoral is 

 inserted at the usual distance from the gill-opening, and has a base of moderate width. 

 Ventrals united and extending to the vent.
