if Mistulipora minor, M‘Coy, be held to be a tabulated coral 
of the Monticulipora group, then Ceramopora megastoma, 
M‘Coy, is only its younger stage; if, on the other hand, the 
latter form be held to be a true Polyzoon, then its later stage 
is only a fuller development of Polyzoal life, and F. minor 
and the other forms indicated in Dr. Lindstrém’s paper in the 
‘Annals’ must of necessity be removed from the Tabulate 
Corals.

XLVII.—Descriptions of two new Species of Birds from 
Sumatra. By Captam R. G. WarpLaw Ramsay, The 
Highland Light Infantry. 
Hemixus sumatranus, sp. n. 
Hypsipetes malaccensis, Salvadori, Uce. di. Sum. p. 57, spec. no. 62. 
A representative of H. virescens (Temm.) of Java, from 
which it differs in having the upper surface, wing-coverts, and 
outer edges of the quills olive-brown in place of olive-green, 
this colour being much deeper on the head ; ear-coverts brown 
with pale shafts; throat, fore neck, and breast like the back ; 
the shaft and a streak down the centre of each feather white ; 
flanks, abdomen, and under tail-coverts white, tinged with pale 
yellow, some of the feathers margined with olive-brown ; 
under wing-coverts and axillaries pale yellow; quills dusky 
brown below, slightly tinged with buff on their inner webs. 
Wings 3:7, tail 3°7, bill from gape °85. 
I obtained this specimen from Count Salvadori in a small 
lot of duplicates of M. Beccari’s collection. It was obtained 
on Mount Singalan, in Western Sumatya. 
Criniger sumatranus, sp. 0. 
Represents C. gutturalis of Borneo and Malacca, from which 
it differs in having the head greyish brown instead of rufous 
brown, the throat purer white, the whole under surface of a 
much darker shade of yellowish olive, and the lower tail-coverts 
deep reddish ochraceous. Size about the same.
