to its living its own, independent life in the same way as K ru ger 
maintains for Smilium Peronii, which he has described in detail 
(1914, p. 431). 
Calantica affinis n. sp. 
25 miles E. to S. of Zamboanga; 200 fathoms, on a siliceous sponge. 
3/ III 14. Several specimens. 
The species is characterised by its rather large latera, which 
overlap each other, and by its nude and short peduncle. (Fig. 4). 
Fig. 4. Calantica affinis from 25 miles E. to S. of Zamboanga. a—c , type in i ostral, 
lateral, and carinal view; d quite young hermaphrodite; e mandible, 1 maxilla ; g 
complemental male. [a—c x 2.7; d X 5,3; e—g X 53]. 
The carina is long, and evenly bent; in dorsal aspect it is 
rather broad, with feebly convex sides; umbo is apical. 
Tergum has an arched carinal margin with a stronger bend 
in the middle; the occludent, and the scutal margins are straight. 
Among the capitulum plates the tergum attains the greater length, 
although it does not very much exceed the carina and scuta. 
The scutum is triangular with straight occludent, and tergal 
margins; only the basal margin is convex, and strongly bent. 
Rostrum is short and broad with recurved apex; in ventral 
aspect it is almost rhomboidal, and broader than high. 
The latera are broad, and triangular; the superior latus with 
its distal free portion covers the lower parts of tergum and scutum; 
its base is overlapped by the carinal, and partly also by the rostral 
latus. A subcarina is present; it has the same triangular shape 
as the latera, and partly hides the basal portion of the carinal 
latera.
