138 Prof. M‘Intosh’s Notes from the 
distinct black eyes occur externally to the base of the 
longer posterior lateral tentacle. 
Body probably three or four inches in length, but only 
about an inch and a quarter of the anterior end and a 
fragment half an inch long of the posterior region are 
present. It is flattened, like that of a Marphysa, and the 
segments are narrow. Little diminution seems to occur 
anteriorly. The first segment (peristomial) is broad, and is 
followed by a narrow one bearing the tentacular cirri, which 
are rather short and subulate. 
Proboscis.—In extrusion (woodcut, fig. 1) the maxillz are 
chocolate-brown, curved in a semicircle, and when viewed in 
profile they are sinuous and bend upwards at the tip. The 
great dental plates have four teeth, the first being longest, 
a large part of the edge behind being smooth. The antero- 
lateral plates have a blackish-brown patch externally in 
protrusion. The right has a long median fang with a bifid 
denticle ventrally, and a long tooth dorsally next it, besides 
a separate denticle or two dorsally. A single large blackish- 
brown patch occurs at the base. On the left are two small 
semicircular blackish-brown touches, the ventral being 
smaller than the dorsal. Dorsally are two long curved 
teeth attached to a separate base; then a curved lamina 
with a long curved fang and a smaller denticle beneath it, 
representing the azygos plate. 
The mandibles have somewhat thick calcareous anterior 
plates with oblque cutting-edges sloping forward and 
outward from the middle line to the pomt, the outer slope 
being downwards and outwards. 
The branchiz commence on the 28th foot as a single 
short filament on each dorsal cirrus. Jn the anterior frag- 
ment of the body, comprising about 63 feet, they never 
attain more than two divisions, which are slender. In the 
posterior fragment three filaments exist in each. 
Looked at generally, the feet are closely arranged—a 
feature due to the narrowness of the segments. The anterior 
dorsal cirri are thicker and more conspicuous than those to 
which branchiz are attached, or apparently than those on 
the posterior region. 
The 1st foot has a somewhat thick, subulate, dorsal cirrus 
of considerable length, a small bluntly conical setigerous 
process bearing a few short dorsal bristles above the spines, 
and below the latter are short compound bristles with 
moderately long tips. The conical ventral cirrus is pro- 
portionally long. Two dark brown spines support the
