•2TA SIR C. ELIOT ON NUDIBRANCHS [NoV. 29, 



DORIDOPSIS SPICULATA, B. 



[See Bergh, Jour. Mus. Godefl". Heft xiv. p. 37.] 



One specimen from Wasin. The notes describe the living- 

 animal as three-quarters of an inch long, high and narrow in 

 shape. The back was covered with numerous small, flat-topped 

 warts and was visibly full of spicules, particularly at the bases of 

 these warts. The colour was white, except for a rov/ of small 

 dark grey spots of irregular shape on each side of the visceral 

 mass and a few other scattered spots. The foot was broad. 



The preserved specimen is of a uniform greyish white ; the 

 skin is hard and full of spicules. The length is 9 mm., the 

 breadth 4, and the height 2*5. The mantle-edge is nari'ow. The 

 back is covered with flat warts, bearing smaller tubercles, and 

 there are also a few simple papillse. The branchial opening is not 

 much raised and slightly crenulate. The branchi^ are six, tri- 

 pinnate, and set in an incomplete circle which is open behind. 

 The foot is pointed at both ends, with uncertain traces of a notch 

 and groove in front. The tentacles are small. 



The internal organs are mostly yellowish and present nothing 

 remarkable. The pericardial lamella? and penial hooks are present 

 «,s usual in the genus. 



This specimen has the main characters of Bergh's D. spiculata 

 -from the Philippines. The difference in form is not remai"kable, 

 as the animals of this genus frequently alter their shape from 

 long and high to flat and broad, but the discrepancy in the number 

 and arrangement of the bi-anchife throws some doul^t on the 

 identification. Bergh's specimen had only four. 



DORIDOPIS PUDIBUXDA, B. ? 



[Bergh in S. R. xvi. 2, pp. 844-5. Cf. id. Jour, des Mus. 

 Godeffroy, Heft xiv. 1878, pp. 33-4.] 



Four specimens from Chuaka. The ground-colour of the living 

 animals was whitish, but almost hidden by two sets of blotches, 

 one of which varied from light reddish brown to deep dark brown, 

 and the other from pale blue to an inky coloui*. The intensity of 

 coloration varied in different specimens, and was also greater in 

 the middle of the back than on the mantle-edges. The mantle- 

 edge changed considerably in shape iind size with the movements 

 of the animal. The branchia? were lined with dark bro\vn and 

 not very sensitive ; the rhinophores dark brown and tipped with 

 white. 



The preserved specimens are stout and high in shape, and have 

 "i-etained their colour fairly well. The largest is 30 mm. long, 

 17 high, and 22 broad. The mantle-edge is crinkled and allows 

 the sides of the foot to be seen. In one specimen it is much wider 

 than in the others, and this specimen is flatter than the others. The 

 back is smooth, arched, and appears to be swollen. The pockets 

 of the rhinophores and bitinchia? are slightly raised and smooth. 

 The rhinophores are somewhat bent backwards and bear about
