.1/. iil'iiii'rpii.<, Chv. A' Val. (Day's Collection) wliicli species lias been uiiitetl 

 with .1/. t'idi' hv KluiiziiiLfer, sliows that it, has a much smaller and 

 narrower head ; it is shorter instead of longer than one-tourth of the lenj^th 

 to the hvpural, and the interocular space is less instead of more tliaii twice 

 the ocular diameter. il/. tadopsis is very similar to J/. piir>'io, Buchauan, 

 with small specimens of which I have compared it, but it has larger scales, 

 there beiu<^ 30 instead of 35 to the hypural joint and their surface sculft- 

 ture is less developeil than in the Jndiau species.

D. iv, i/8 ; A. iii/9 ; P. 15 ; V. i/5 ; C. 14. 31-32 scales between the 

 operculum and the hypural joint, and 12 between the back and the belly 

 before the first dorsal fin exclusive of the medium dorsal and ventral rows. 



Depth before the first dorsal fin 3*4 in the length to the hypural 

 joint ; head 4 in the same. Eye 37 in the head, equal to its distance from 

 the premaxillaiy symphysis, and 14 in the interorbital space, which is 

 28 in the head. Least depth of the caudal peduncle 19 in the head. 

 First dorsal spine 1'9, second dorsal ray 1'7, and pect(n-al fin LI in the 

 head. 



Upper and lower profiles of the head and body almost equally arched. 

 Head deeper than broad. Snout rounded in the horizontal plane, its 

 upper profile convex. Upper lif) lather broad and vertical ; a few very fine 

 ciliae on the [)remaxillaries. Mandible very thin, without teeth, its rami 

 meeting at an obtuse angle. Maxilla small, not quite reaching the vertical 

 of the anterior orbital border, and completely hidden beneath the pre- 

 orbital when the mouth is closed. Preorbital notched and denticulated on 

 its anterior and posterior margins ; its upper surface with a few scales. 

 Adi})ose eyelids well develope<l but not encroaching upon the pupil. 

 Cheek-scales finely ctenoid, arranged in five j-ows below the eye ; small 

 scales extend over the snout and mandible, and become lai'gei- and ciliated 

 on the operculum. 



Body scales obscurely ciliated, almost cycloid, but ctenoid on the 

 breast. They are without membranous borders and are largest on the 

 middle of the sides. Axillary scales well developed, reaching along one- 

 third the length of the pectoral; the exobasal scales of the ventrals and 

 spinous dorsal ai'e also consf)icuous. The bases of the pectoral and caudal 

 fins are completely covered by scales which also extend up between the 

 raj-s ; a .scaly sheath covei s the base of the anal ; and scales extend up 

 between both the dorsal and anal rays but do not conceal them.
