Family CancellariidsB. 



354. Cancellaria {Merica) asperella, Lam. 

 Loc. Seychelles : Station F 3, 39 fathoms, hard sand. 



355. Cancellaria {Euclia) lactea, Desh. 



Loc. Saya de Malha Banks : Station C 1, 150 fathoms, on white-rubble ground of 

 dead coral, &c. 



Order AMPHINEURA. 



Suborder POLYPLACOPHORA. 



Family ChitonidsB. 



356. Schizochiton incisus (Sowb.). 

 Loc. Coetivy I. 



Saya de Malha Banks : Station C 16, 26 fathoms, on living corals and rubble. 



Arairantes : Station E 2, 29 fathoms, on living corals and rubble. 



Chagos Archipelago : Egmont Atoll reef. 

 The specimens obtained from the above stations are moderate in size and seem akin 

 to the var. elonyatus, Heeve (sp.). Mr. E. A. Smith records this species as obtained for 

 the first time in the Indian Ocean at Addu Atoll, Maldives, on Mr. J. Stanley Gardiner's 

 first expedition. 



*S'. incisus will always be considered one of the most interesting of the ChitonidiB, since 

 the late Prof. Henry Nottidge Moseley, F.R.S.*, first noticed the presence of dorsal eyes 

 on its surface in 1883. 



357. Acanthochites [Loboplax) laqueatus (Sowb.).

Loc. Amirantes : Station E 13, 20 to 25 fathoms, calcareous rubble. 



Also from Mindoro I., Philippines, and Maldive Islands {J. Stanley Gardiner). 



Mr. Edgar Smith's remarks on this species (/. c. p. 620) are of much interest. 



358. Acanthopleura borbonica (Dcsli.). 



Chiton borbonicus, Deshayes, Moll. Reunion, p. 37, Taf. 5. figs. 13, 13. 

 Loc. Seychelles: Praslin I. 

 Fine, well-developed specimens, and presumably locally common. 



N.B. — Three very small specimens of this Order, about 5 mm. in length, and most 

 probably all undeveloped, non-adult species — (a) from Chagos Archipelago, Peros 

 Banhos, (6) Coetivy, 32 fathoms, (c) Amirantes, Station E 2, 29 fathoms,— have, at the 

 recommendation of two specialists in Chitonidte, been left undifferentiated.
