Serupocellarta reptans var. Bertholletii, Waters, “ Bry. from Rapallo,” Journ. Linn. Soc., 
Zool. vol. xxvi. (1896) p. 6, pl. 1. figs. 18, 19. 
I have already shown how the characters correspond with those of 
S. reptans, L., in which, however, the scutum is usually more developed, 
though in these two forms we seem to have a pretty complete range from 
zocecia without a scutum to those with a broad scutum protecting the 
whole area. It is, however, perhaps more convenient to retain the specific 
name of Berthoiletii. 
Loc. Naples, Capri, Rapallo, Trieste, Cape Verde Islands, Suez (9), and 
underside of buoy (14), collected by Crossland. 
SCRUPOCELLARIA SERRATA, sp. nov. (Plate 10. figs. 11-14.) 
Zoarium with narrow branches, and short internodes having 5-8 zocecia. 
Zocecia long and narrow, area about half the length of the zocecium, with 
two outer spines and one inner; the scutum is delicate and cervicorn, 
eco, 
in S. Bertholletii, Aud. There are no median, and to most zocecia no 
ranging, however, from the simple spine to the multi-cervicorn forms as 
lateral avicularia, nor are there any vibracula; however, to some zocecia 
standing out from the side just below the ovicell there is a large avicularium 
(fig. 11), and these have long narrow mandibles, which are bifurcate or 
trifurecate at the end, with spinous processes at the side (fig. 14). Some 
pieces have no avicularia. S. varians, Hineks, and S. obtecta, Haswell, also 
have a large lateral avicularium. ‘The radicle is attached to a chamber close 
to the base of the zocecium and is thin and serrate. Busk mentions the 
radicies of S. Macandrez, Busk, and S. ferov, Busk, as being serrate. The 
globular ovicells are perforated. There are 14 tentacles. 
This species has the habit and many of the characters of S. Bertholletir, 
Aud., but differs from it in having, asa rule, no avicularia and no vibracula. 
Loc. Suez, about 5 fath., collected by Crossland.
