ON THE ICHTHYOLOGY OF THE SEAS OF CHINA AND JAPAN. 315 
Morinct'Aa ——? Temm. et Schl. 
The British Museum possesses a Japanese Moringua of which we do not know the specific 
name, as the lable originally attached to it had been transposed before it was purchased by 
the museum. It differs from M. lumbricoidea in its more slender, elongated body, narrower 
fins and longer under-jaw. The rays are perceptible round the end of the tail only, the rest 
being concealed by the thickness of the membrane. The teeth are similar to those of lum- 
bricoidea. Though the specimen is 264 inches long, it is no thicker than a lumbricoidea only 
ten inches in length. The genus seems to be the same with Ptyobranchus of J. M‘Clelland, 
but his Indian species all differ in the shape of the fins.

We are ignorant of the internal structure of this fish, but from the posterior position of the 
anus it is probably to be referred to the Sphagebranchide of Miiller (Ophicardides, M’Clelland). 
A stuffed skin exists in the Haslar Museum, which was brought from China by Commissioner 
Elliot.

On consulting Mr. M‘Clelland’s paper in the 18th number of the Calcutta Journal, I find 
that,"misled by the close similarity of the outline of Pneumabranchus cinereus in the fourth 
volume of the above-mentioned journal to that of this Chinese fish, I erred in considering 
them to be the same species. This fish has a naked skin, while the bodies of his Pneuma- 
branchi (Amphipnous, Miller, 1840) are covered with imbricated scales.

Monorrervus MARMoRATUS, Temm. et Schl. ( Unibranchapertura). 
The British Museum possesses an example of this species which was procured by Dr. Cantor 
at Chusan. It is 17} inches long, the part behind the anus measuring 3°45, and being con- 
sequently proportionally a little shorter than the tail of either levis or cinereus, The head is 
decidedly larger than in either of these species, and when measured to the posterior corner of 
the gill-opening, rather exceeds a tenth of the whole fish. A deep furrow runs along the middle 
of the back, which is narrower than the belly from the head to opposite the anus, and the 
action of the muscles produces a furrow coincident with the lateral line, which disappears 
when the parts are stretched. The belly is rounded. The lateral line in the middle of the 
height is composed of a series of very fine grooves, and is darker than the neighbouring parts. 
The tail is edged above and below by a very narrow translucent seam of pale skin entirely 
destitute of rays. 
The ground colour, after maceration in spirits, is wood-brown, thickly speckled on the 
head, back and sides with dark umber-brown. On the top of the back the umber-brown specks 
aré atranged so as to produce three lines, one occupying the mesial groove, and the other two 
the ridges on each side. On the sides the specks produce two series of short curves which 
meet at the lateral line in an angle and seem to correspond with the fasciculi of muscular
