These specimens agree very closely with the figures and description given 
by SARS for Podocerus falcatus (1894, pl. 212) as regards the males and also 
the females. The tube marked »On a buoy in Cumberland Bay,» contains a 
great many specimens, mostly young, though there are a few fully developed 
males and females. Among the young males are several showing some of the 
stages in the development of the adult characters, all of which can be paral- 
leled by specimens obtained in similar situations in New Zealand. The species 
is very widely distributed both in northern and southern seas and includes a 
number of forms towards the full life history of which notable contributions 
have been made by Mrs. E. W. SEXTON of Plymouth.

Horcali tye 
Masatierra, Cumberland Bay, 20—25 m., 6. XII. 16. No. 53. Several 
specimens, males and females, the longest being about 10 mm. long. 
These specimens agree well with the description given by DANA and must 
I think be referred to his species. The following appear to be the important 
characters. The head bears a well marked acute tooth projecting forwards and 
a little upwards. The second gnathopod of the male (fig. 4, C) is somewhat 
elongated with the propod oblong, the palm nearly straight, defined by an 
acute tooth, having another acute tooth a little distal of the middle of the 
palm, followed by a truncate projection with minutely crenated edge near the 
base of the finger. In an ovigerous female the second gnathopod (fig. 4, B) 
has a similar shape but is somewhat smaller and the acute tooth near the 
centre of the palm is absent or only very slightly represented. In both sexes 
the basal joint is fairly long and has the upper margin produced into a thin 
flange which projects at the distal end in a subacute tooth. The branchiae 
are narrow-elliptical. 
In addition to the points already mentioned the specimens agree with DANA’s 
fuller description of minor points. The upper antennae are fairly long and 
have the flagellum composed of nearly 20 joints, the first three or four of 
which are united into one as described by DANA. The inferior antennae are 
about as long as the flagellum of the upper, the two-jointed flagellum being 
equal in length to the preceding joint. The first gnathopod (fig. 4, A) is about 
the same in male and female, and has the propod somewhat triangular, the 
palm occupying the whole of the posterior margin, slightly convex and fringed 
with long setules, a few setules arising also in a row parallel to the anterior 
margin. In some specimens examined the third and fourth segments have the 
pleura produced downwards into a prominence similar to that mentioned by 
DANA except that is not quite so regularly oblong, being deeper posteriorly. 
The species also shows a very close resemblance to Cafrel/a dentata 
Haller as described by MAYER in 1882, the gnathopods being apparently in
