Radula. Wlien removed and flattened the radula measured 5 mm. by 
3"25 mm. and was large and well developed for the size of: the animal. The 
total number of rows in the radula was 83-85, and the number of teeth in 
each row : — in the first row 20 . . 20 (i. e., 40) ; in the tenth row 72 . . 72 
(?'. e., 144) ; and in the eightietli row 76 . . 76 {i. e., 152). There is no rachidial 
tooth. The innermost teeth are small but stout, and consist of an elongated 
base with a marked hook, on the side of which area series of from 4-6 small 
triangular denticles. The teeth increase in size as they pass outwards and 
the hook becomes larger, bearing on its inner curved edge a series of 6—8 
denticles and terminating in a rounded point. The outermost teeth are 
slightly smaller than those nearer the middle of the row. They have their 
bases much smaller, and the denticles are reduced to one or two blunt pro- 
jections near the end. 
The genital aperture is placed high up on the anterior end of the right 
side of the bodj^. 
Notes. In all there were six specimens in the collection : three were from 
the Abrolhos Islands with no further details ; two were from the shore of 
Wooded Isle, one of which had the pharynx exserted ; one was from the 
shore of Long Islandj and this was very dark in colour. 
It does not appear to correspond with any previously described form. 
Genus Aphelodoeis Bergh, Malakozool. Blatt. 1879, p. 107. 
Type by monotypy : A. antUlensis Bergh, ibid. p. 108. 
In outward appearance these forms very closely resemble the Grlossodorids, 
and have a well-developed notseum beyond which the tail projects. The 
uiantle-edge only projects a very short way. The foot is fairly small, rounded 
in front, and not very sharply marked off i\\ m the body. The rhinophores as 
in Glossodoris. The oral tentacles are short and stunted, and have a cleft on 
their underside. The retractile gills are composed of a few (5) tripinnate 
plumes. The lips are only covered with a moderately thick euticula. There 
is no rachidial tooth, and the pleural teeth are numerous and hamate. Only 
a posterior blood-gland is present. The prostate is large and the penis 
unarmed.

Body. The shape of the body is typical of the Glossodorids. The notajum 
is a moderately long oval with its long sides approximately parallel and the 
ends equally rounded. It is carried over all round into a narrow paliial 
ridge. The body is fairly stout and its sides almost upright, running down 
to a moderately wide foot. The lower part of the body extends out beyond 
the notseum as a tail.
