PROF. THOMSON AND MR. McQUEEN—REPORT ON THE ALCYONARIANS. BYS) 
(2) Smooth spindles with only a few spines: 1:02 x0:15 ; 0°72 0:15 : 
0:6 x 0-075 ; 0°55 x 0:075 ; 0°42 x01 ; 0-40:05; 0:275 x 0°04 ; 
0:2 x 0°05. 
The colour of the colony in spirit is light yellow. 
Locality.— Khor Dongola. 
NEPHTHYA ZANZIBARENSIS, Thomson and Henderson. 
See Thomson and Henderson, 1906, loc. cit. p. 421, pl. xxvii. fig. 3. 
A specimen which seems to be referable to this species differs from the 
type in being distinctly more rigid; that is to say, more densely filled with 
spicules. 
Locality —Hngineer Island, Khor Dongola. Previously recorded from 
Wasin Channel, Zanzibar. 
N#PHTHYA ALBIDA (Holm). 
= Sponyodes albida, Holm. 
See O. Holm: “ Beitrige zur Kenntniss der Alcyoniden-Gattung Spongodes,” Zool. 
Jahrb. viii. (1895) p. 30, 3 figs. 
See Kukenthal, 1905, doc. cit. p. 160. 
A specimen which seems referable to this species differs from the type in 
having the polyp-body covered with very numerous small spicules without 
definite arrangement in double rows. In other words, the larger polyp- 
spicules arranged in chevron are not represented. In including Nephthya 
jagerskioldi with Spongodes savignyi, Kiikenthal notes the same kind of 
variation which we believe to have occurred here, namely a replacement 
otf fewer larger spicules on the part of the polyp-wall by more numerous 
smaller spicules. This cannot be regarded as of systematic importance. 
Locality.—Suakim Harbour. Previously recorded from the Red Sea.

Nephthyiden, 2 Teil,” Zool. Jahrb. xxxi. (1905) pp. 503-726, 7 pls. & G1 figs. 
Several colonies in the collection are evidently referable to a group of 
species which Kiikenthal speaks of as closely allied, namely, 5. hartmeyeri, 
S. mayi, S. klunzingert, S. ehrenbergi, and S. hemprichi. 
* According to Kiikenthal, the generic name Spongodes should he replaced by another, and 
he suggests Dendronephthya; see page 74.
