A small papilla tlirowi"! off by this 7 mm. spccimm 
continued for 24 hours to make automatic vital movements. 
The radula in this specimen had 4^ rows of teeth, ard all 
of the Dublin specimens agreed perfectly in colour with 
Hancock's plate in the Monograph. 
Coryphella rufibranchialis (Johnston). 
Eolis riifibranchialis. 
Rare ? Dublin Bay, not uncommor; : Hassall, '42. Two 
iuvenile specimens 5 mm. in length dredged in 10 f. off 
Skerries, July, 1912 : N .C. 
C. gracilis (Aid. and Hanc). 
Eolis gracilis. 
Not infrequent. Dredged six times in July, 1913, live 
times off the Skerries islands in from 2 to 15 f., a total of 
10 specimens, and once in 14 f. off Dalkey, a single specimen. 
The specimens ranged in length from 3 to 6 mm., and the 
papillae w^ere a clear orange rather than the reddish brown 
tint shown in Hancock's plate. One specimen, 13 mm. in 
length and spawning taken on Halecium halecinum in 5 f. 
off Kingstown East Pier, May, 1914 : N.C. 
The rows of teeth in the radulae of three specimens dis- 
sected varied in number from 10 to 14. There were usually 
5 denticles on either side of the large median teeth, and 
from 6 to 8 in the laterals. The spawn coil of the largest 
specimen measured 25 mm. when extended with a width 
of hardly i mm. and was constricted at intervals like the 
coil of Eolis papulosa. The eggs which were arranged 
usually in 4 rows, numbered on a rougli count 1,500 for the 
whole coil. The rounded-elliptic otoliths were found to 
be about 25 in number. 
C. Landsbergii (Aid. and Hanc). 
Eolis Landshurgi. 
Rare. Of this species, perhaps the most beautiful of all 
our Eolids, a juvenile specimen 5-5 mm. long was dredged 
in Malahide River attached to the conunon sponge Halichon- 
dria panicca in about 2 f. in September, 191 1, and another,
