its cyclosystems separate it widely, even from small speci-

Distichopora livida, 'Venison- Woods. 
‘This species was first described by the Rev. J. E. Tenison- 
Woods, in the Proc. Linn. Soc. New South Wales, vol. iv. 
1879; and in his valuable monograph of the genus (Journ. 
Roy. Soc. N. S. Wales, 1879) that author gives further 
details of its structure. It is to be regretted, however, that a 
more definite term than ‘ livid” was not given in the de- 
scription of the colour of the main portion of the coenosteum, 
since this furnishes such a valuable help in the determination 
of the species. Judging by specimens in the British-Museum 
collection, which seem to belong to this species and of which 
the locality is unknown, the colour varies considerably from 
dull or pale purplish red to dull reddish or brownish orange, 
having the extremities, as given in the description of the 
species, white, yellow, or orange, and the lateral furrows and 
incipient branchlets bright red or orange. If this identifica- 
tion is correct, it will be seen how closely this species is re- 
lated to, if indeed it is distinct from (which may fairly be 
doubted), D. nitéda, Verrill, which comes from the same 
locality, and the description of which Tenison- Woods had had 
no opportunity of consulting. If, however, the strict meaning 
of lividus was intended, ¢. e. bluish or black and blue, then this 
species presents a most remarkable variation in colour, and 
certainly would seem to be distinct from any yet described ; 
and although stated to be very common in collections made 
in the neighbourhood of the Solomon and Marshall Islands, 
it is absent from the large and very fine collection of Stylas- 
teridz in the British Museum.

It seems advisable to state here, in order to prevent mis- 
understanding and further complication in the synonymy of 
the species, a few facts concerning the characters and distribu- 
tion of D. nitida, V., which must have been known to any 
one who had read the description of the species. 
The specimens of D. nitida described by Verrill in the 
Bull. Mus. Comp. Zool. vol. i. no. 3, published in 1864, were 
collected by A. Garrett, at Ebon Island (Marshall Islands), 
and although described in the old terminology before the 
brilliant researches of Prof. Moseley revealed the true nature
