present the abrupt transitions seen in Loridopsis mammosa, and is of 

 a more uniform breadth, but its essential structure seems to be the 

 same. It shows one constriction at the point where the buccal ganglia 

 are set and a second just before it enters the liver. After this second 

 constriction comes a small globular dilatation. 



The intestines are pale yellow. The liver is very large, cleft 

 behind, and extending right into the anterior part of the body, where 

 it lies under the buccal organs. It is somewhat lighter outside owing 

 to the layer of the hermaphrodite gland which covers it. The 

 genitalia are small. A prostate is present. The vas deferens and 

 glans penis are very thickly covered with minute, slightly bent spines, 

 resembling the hamate teeth of Dorids, but rather more elongate. 



This form closely resembles BoridopaiH fulva of MacFarland (Xudib. 

 Moll, of Monterey Bay in Bull, of Bureau of Fisheries, Washington, 

 vol. XXV, p. 130, 1905). If thev are identical, Cheeseman's name 

 (1880) has priority. 



GONIODORIS PUNCTATA, B. 



Goniodoris punctata, Bergh : Mai. Unt. in Semper' s llcisen, vi, 2, 

 p. 91, 1905. 



Two specimens from Akaroa Harbour, near Lyttelton, in the South 

 Island. They are about 6*5 mm. long and of a uniform yellowish- 

 green without any trace of the red spots found in Bergh's specimens. 

 The dorsal margin has a jagged appearance, as it is marked by a line 

 of 7-10 simple lancet-shaped processes on each side. Similar processes 

 are found on the frontal margin. On the dorsal surface are scattered 

 tubercles, about 5 in front of the rhinophores and 20 between the 

 rhinophores and branchias. The part behind the branchia; is smooth. 

 The tubercles form three extremely irregular rows, of which that in 

 the middle is most definite. Bergh describes it as a Kamm, but it is 

 evidently not so well developed in my specimens as in those which he 

 examined. The head is produced into a blunt projection on either 

 side. The foot is not grooved in front and not produced at the 

 corners. The rhinophores are rather large ; they bear about 10 

 perfoliations and show no trace of sheaths or pockets. The branchiee 

 are 5 or 6, scanty and bipinnate. 



The internal organs are as described by Bergh. On the labial 

 cuticle is a ring (apparently consisting of two semicircles which 

 nearly meet) composed of small rods with tips sometimes entire and 

 sometimes divided. The formula of the radula is 31 x 2 . . 2. The 

 teeth are transparent. The inner tooth is large and bears at least 20 

 denticles. The outer tooth is a small plate, bearing in most cases 

 a single low but distinct cusp.

One of Abraham's specimens examined. The external characters 



are as described by him. The dorsal papillae are somewhat longer 



ttian usual. Two of the denticulations on the rhinophore sheath are
