328 PROF. H. H. GIGLIOLI ON A NEW GADOID [June 18, 



These projections had been taken by an automatic electro-pho- 

 tographic apparatus with a regulated and exactly equal period of 

 time between the phases, which are photographed synchronously 

 from two or more points of view. With this apparatus thirty-six 

 illustrations had been made of a horse while jumping a hurdle ; each 

 of twelve phases illustrating the complete action having been simul- 

 taneously photographed from the side, front, and rear. Twenty-four 

 consecutive phases of the wing of a bird while flying had also been 

 photographed, the time-intervals of each successive phase being 

 recorded by an electro-chronograph.

(Plate XXXIV.) 



Eretmophorus\ gen. nov. 



Body moderately elongate, tapering in older specimens towards 

 the tail ; covered with small adherent cycloid scales marked with 

 concentric lines, and not extending to the head and abdomen, which 

 are naked. Abdomen prolonged in a great cone, much more developed 

 in the older specimens ; at its extremity, nearly opposite to the 

 small first dorsal fin, is the anal aperture and behind this a sniall 

 conical papilla. A separate caudal, lanceolate in the younger specimen, 

 subtruncate in the older one ; two dorsals and one anal fin ; the 

 second dorsal and anal largely and equally developed. Pectorals 

 lobate ; ventrals jugular, singularly developed, with five rays, three 

 of which, and more especially the third and fourth, are greatly 

 elongated and furnished at the endtuith a beautiful lanceolate paddle- 

 like blade. Vertex of head and naf)e with small hyaline cyhudrical 

 warts. Teeth very small, few and iucous})icuous, on premaxillae and 

 end of mandible. Branchiostegals seven. No barbel.

Brs. vii. 



Body compressed, tapering towards the tail, but less so in the 

 younger specimen, in which the huge and singular abdominal cone 

 is also less developed. The height of the body behind the abdominal 

 cone is contained between 5g and 6 times in the total 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 

 ^ 'Eper/ios (remus), oar ; <popos (ferens), carrier.
