Atjeh (W. Baerts, 1887). — The cirri are XXII, 32 
— 34 (usually the latter), bearing sharp dorsal spines from 
the tenth or eleventh segment onward; the synarthrial 
tubercles are developed as in the type of A. pinniformis. 
The size is slightly less than that of the type of A. mol- 
leri at Copenhagen.

Andai: New Guinea. — This is a small species of 
Amphimetra, of the milberti-division of the genus. The cirri 
are moderately stout, tapering slightly in the distal half, 
with all the segments subequal, about twice as broad as 
long, those in the proximal half slightly longer, those in 
the distal half slightly shorter. The synarthrial tubercles 
are rather prominent, though small, as in specimens of 
Amphimetra discoidea from Port Molle, Queenslanc. P, is 
much larger than the small and weak P,, and is long 
and stout; P, is similar to P, and nearly as long and 
stout; the following pinnules are small and weak; the cirr 
are XII, 25; the dorsal spines on the outer segments are 
sharp and long.
