new and rare British Copepoda. B57 
Dermatomyzon gibberum, T. & A. Scott. 
(Pl. XVI fe” 14.) 
This species was described in the Ann. & Mag. Nat. Hist. 
for February 1894; at that time only a single specimen had 
been obtained from a tow-net gathering collected near the 
mouth of the Firth of Forth. This year (1895) we have 
taken aconsiderable number of specimens of the same species, 
not only in the Firth of Forth, but also in Liverpool Bay ; 
they were obtained by washing a number of specimens of the 
common starfish (Astertas rubens) in a bottle containing 
methylated spirit mixed with water, and afterwards exam- 
ining the sediment. Several of the specimens from both 
localities were apparently mature, and a few of them carried 
ovisacs; these apparently adult forms differed in general 
appearance from the one figured in the Ann. & Mag. Nat. 
Hist. in being more globose in outline; but a careful dissec- 
tion and examination of one or two of these adult specimens 
showed that this was the only difference of importance; the 
structure of their various appendages was apparently identical 
with the structure of the appendages of the specimen first 
described and figured in February 1894. We, therefore, at 
the present time do not think it is necessary to repeat these 
structural drawings, but, instead, we give here a full-size 
drawing of one of the adult forms from Liverpool Bay (see 
fig. 14), as the full-size figure in the Ann. & Mag. Nat. Hist. 
for February 1894 is evidently that of a somewhat immature 
specimen. 
Alcyonicola fusiformis, gen. et sp. n. 
(Pl. XVI. figs. 10-14; Pl. XVII. tig. 13.) 
Description. Body elongate-fusiform ; the last two abdo- 
minal segments distinct, all the others coalescent. Head 
somewhat produced and furnished with both antennules and 
antenne. The abdominal segments are unequal in length, 
the penultimate one being nearly four times longer than the 
other, which is very short. Cuandal stylets well developed 
and equal to about three fourths the length of the penultimate 
abdominal segment; they diverge considerably, and each 
stylet is provided with three stout spiniform sete, which are 
at least three times the length of the stylet; the middle one 
is straight, but the one on each side diverges at the base and 
then curves round towards the end of the middle seta; each 
stylet has also one or two small hairs on the lateral aspect. 
Fig. 13, Pl. XVIL, is a full-size drawing representing a dorsal 
view of one of the more perfect specimens of this Copepod.
