with a minute exterior lobe. A membranous flap overhanging the lips 
covers the posterior nostril, which is situated just before and below the eye. 
Teeth cardiform, in a single row in the jaws, and a median row on the 
palate. A few longer ones are found on either side of the vomer covered 
by the lips. The anterior teeth of the mandible are a trifle longer than the : 
posterior ones. A row of 3 pores on either side of the snout before the 
eye, another row of 3 on either side of the mandible. A single one on to 
of the head nde the eyes, and another single pore on the latera! hne 
above the gill-opening. Tongue immovable. ill-opening small, about as 
wide as the eye; branchiostegal sac not greatly developed. Lateral line 
somewhat nearer the dorsal surface than the middle of the height ; slightly 
arched above the branchial sac, thence ocu downward towards the 
angle of the mouth, which it does not quite re 
Vent placed nearer the head than the tip of tail, its distance from the 
snout being rather less than 1-4 in the tail. 
f dorsal fin a little posterior to that of the anal, and the distance 
from its origin to the vent about half the length of the head. Both fins 
are exceedingly low, almost rudimentary, but they broaden out slightly 
near the tip of the tail, which they surround. From the dorsal origin a 
. groove is Bee all along the middle of the back, ending near the nape.

Described and figured from a living specimen, 247 mm. long, which was 
captured in Whangarei Harbour, Auckland District, by Mr. W. M. Fraser, 
Engineer to the Whangarei Harbour Board. Mr. Fraser informed me that 
e found it at a depth of 9 in. below the surface 'of a sandy mud-flat at 
low-tide mark, where the common marine grass grows. 
Affinities. — The species was first described and named by Macleay from 
specimen captured at Port Jackson, and later redescribed and figured 
by McCulloch from Macleay’s original specimen. The only other one of 
this genus so far known to occur in New Zealand, and recorded by me in 
Trans. N.Z. Inst., vol. 53, p. 351, pl. liv, fig. 1, 1921, is M. breviceps, which 
has several marked specific differences, particularly ‘those in regard to the 
position of the dorsal fin and the form of the teeth. In M. breviceps the 
origin of the dorsal fin will be found not far behind the head, while its teeth 
are granular.
