is found in all the teeth except the last three, which are thin and 

 irregular in shape, but not serrulate. The oesophagus is thin and 

 rather wide. The large stomach lies in front of the liver, and is not 

 at all enclosed in it. In the British Museum specimen its upper wall 

 is strongly laminated. Beneath the stomach lies the ratlier large gall 

 bladder. The liver is shorter than in ordinary Dorids, and abruptly 

 truncated in front where the stomach and hermaphrodite gland tit 

 into it. 



The hermaphrodite gland does not form a layer over the liver as 

 usual in Dorids, but is a separate yellowish mass about 15 mm. long 

 and 10 broad. The ampulla of its duct is moderately large ; the vas 

 deferens is not much convoluted, but lies in one long loose coil. Tlie 

 part nearer the bifurcation of the male and female branches is soft and 

 glandular, but not dilated. The lower part is muscular and begins 

 with a very small swelling. The end of the vas deferens and the 

 glans penis are armed with minute hooks, rather thick in shape, but 

 often with pointed tips. The verge terminates in a sharjdy defined 

 tip, which may perhaps have been a hard tube in life. The spermato- 

 theca is spherical, greyish, with thin walls and a short duct, whereas 

 the spermatocyst, which rises close to it, is yellow, with thick tough 

 walls and a rather long duct. 



This species is undoubtedly an Alloiodoris, and Abraham's specific 

 name has in any case priority. Bergh's A. marmorata is perhaps 

 a distinct species. The first lateral tooth is differently formed ; no 

 labial armature was found, and it is not mentioned that the tentacles 

 are grooved. It is not clear that the animal figured by Basedow & 

 Hedley is either A. marmorata or A. lanuginata. It differs somewhat 

 in coloration, and they state that the teeth were not denticulate. Thej' 

 say nothing about the hermaphrodite gland.

 One specimen almost rolled up into a ball, but with external 

 characters corresponding, as far as they can be seen, with previous 

 descriptions. It is labelled Boris JVellmgtonensis, and as preserved is 

 27 mm. long and 25 mm. broad. 



The central nervous system is pinkish and much concentrated, the 



separate ganglia being hardly distinguishable either from above or 



below. The eyes are sessile. The blood-gland is pinkish white, much 



branched before and behind. The salivary glands are band-like and 



very long. The radula consists of 33 rows, of which the first three 



' are fragmentary and the last tw^o imperfectly developed. There are 



I from 55 to 65 teeth on either side of the rhachis. There is no 



rhachidian tooth, as erroneously stated by Hutton. The first 15 teeth 



h' on either side are rather low, with long bases and short, strongly bent 



shafts. The rest are more erect, slender, with long sluifts hollowed 



' out on each side near the base, so that the lower part of the back 



^ is a mere lamina. The three outermost are thinner and smaller.
