latter does not consist of two spherical masses as here, but of two short thick coils spread 

 over the top anterior part of the liver. 



23. Flocamopherus iudicus, Bergh. 



Bergh, Mai. Unters. in Semper's Keisen, Heft xvii. pp. 954-958. 



One specimen from Coetivy: 26 mm. long, 9 mm. high, and 7 mm. broad. The 

 colour is pale lemon-yellow, sprinkled everywhere with greyish spots. The oral veil 

 is moderately large, but no appendages are visible; the caudal crest is also modei-ately 

 large and jagged. The rhinophores are large and brown ; the branchiae three, small 

 and brownish. Along the mantle-edge are traces of one or two retractile papillae. On 

 either side there is a single extrabranchial appendage, not branched, but, as preserved, 

 globular in shape and pinkish brown. 



The labial armature consists of two plates formed by fibrous-looking, pale yellow rods. 

 Owing to the faintness of its colour this armature is not at all conspicuous, but it is in 

 reality fairly large. The formula of the radula is 24.X12+11 . . ll-j-12. The 

 rhachis is broad and marked by transverse lines. The first eleven teeth are hamate ; 

 the twelve outermost are mere plates. 



In spite of some difi'erences in the colour and labial armature, I think this is a light 

 variety of Bergh's PL indicus. 



24. Doridopsis nigra, Stimpson. 



See Eliot, in Proc. Zool. Soc. 1904, vol. ii. pp. 275-6. 



This common species is represented in the collection by three specimens from Coetivy, 

 two of moderate size and one small. They are not well preserved, but appear to belong 

 to the greenish-black variety with indistinct borders and spots of a paler colour. 



25. Doridopsis sp. 



One small specimen about 10 mm. long, from Coetivy, of a yellowish -white colour. It 

 is perhaps an immature Doridopsis rubra. The buccal parts are as in that species. 



26. Dhyllidia varicosa, Lam, 



One specimen from Salomon Atoll. It has the typical form and coloration. It is 

 about 41 mm. long, glossy black, with bluish ridges bearing yellow tubercles. The 

 three central ridges are straight and distinct, only uniting near the end of the body. 



Another specimen was obtained in Passe Dubois, Aldabra. 



27. Fhyllidiopsis carinata, sp. nov. (Plate 25. figs. 8, 9, 12.) 



One specimen from Amirante E 16, 39 fathoms. 



The length is 19 mm., but as the specimen is bent this probably represents 22 mm. or 

 more. The breadth is 15 mm. 



Down the centre of the back runs a crest bearing tubercles, the tallest of which is 

 about 3 mm. high. The tubercles are conical and often compressed laterally, so that the
