Cdochilus scpUmtrionalis (Goodsir); Brady, Nat. Hist. Trans. Northum- 
berland and Burliam, vol. i. p. 32, and Intellectual Observer, vol. vii. p. 7, 
from all round Britain. 
Calamts anglicm (Lubbock), Brady, Intell. Observ. vii. p. 8 ; C. Jinmar-

pi. 1. figs. 1-11, 13, from Shetland, Durham, and the Channel Islands. 
Varacolanus^ g. n,, Boeck, 1. c. p. 8. This genus corresponds with Calanm 
of Claus. Paracalamis parvus (Claus), Boeck, 1. c. p. 9, from Norway. 
Clausia, g. h., Boeck, 1. c. p. 9. Body long. Cephalon connected with the 
first somite of the pereion, anteriorly produced into a short and robust fron- 
tal horn. Fourth and fifth somites of the pereion joined together. Pleon 
formed as in Calanus. C. elongata, sp. n., Boeck, 1 . c. p. 10, from Christiania- 
fjord. 
Candace norvegica, sp. n., Boeck, I, c. p. 11, from Norway. ' 
Buclueta prestandrea (Phil,), Boeck, l.c. p. 12, from Norway. 
Dias hngiremis (lallj.), Boeck, 1. c. p. 13, from Norway ; Brady, Nat. 
Hist, Trans. North. & Durham, vol. i. p. 35, pi. i. fig 14, and pi. ii. 
fig. 11-18, and Intell. Observ. vol. vii. p. 8, pi. i. fig. 3, from Durham, Isle

Metridia, g. n., Boeck, 1. c. p. 1-3, Resembling Pleiiroma (Claus), from 
which it difiers in having the first somite of tlie pereion not joined with the 
cephalon, and in having the inner ramus of the pereiopoda triarticiilate. The 
characteristic pigment belonging to the maxillipeds is wanting in this genus, 
the males of which have but a simple eye. The species of this genus, with 
movement, give forth a phosphorescent light. M. lucenSy sp. n., Boeck, 1. c. 
p. 13 ; 31. armala, sp. n., Boeck, 1. c. p. 14, both from Norway. 
Temora longicornis (Miiller), Boeck, 1. c. p. 16, from Christianiafjord. Dr. 
Boeck states this to be the same as T. Jlnmarchica of Baird, but not Mono- 
etdus Jinmarchicus of Gunner. It is also the same as Diaptomus longicaudatus 
•of Lubbock. — T. Jinmarcliica (Gunner), Brady, Nat. Hist. Trans. North. 
& Durh. vol. i. p. 36, pi. i. fig. 15, and pi. ii. fig. I-IO, from Shetland and 
the Channel Islands ; T. velox (Lillj.), Brady, 1. c. p, 38, and Intell. Observ. 
vol. vii. p. 9, pi. i. fig. 5, from Cumbrae and Sunderland ; and Boeck, 1. c. 
p. 17, from Norway. 
Temora inertnis, sp. n., l^oeck, 1 . c. p. 16, from Norway. 
Istas, g. n., Boeck, 1. c. p. 17. This ^enus resembles Leuckartta (Claus), 
from which in some degree it is separated ; it also resembles Centropages 
(Kroyer). The cephalon is separated from the first somite of the pereion, 
whereas the fourth and fifth are united. The pleon in the male has five 
somites, in the female three. I. clavipes, sp. n., Boeck, 1. c. p. 18, from 
Norway. 
Centropages (Kroyer) Dr. Boeck (1. c. p. 18) states to be synonymous 
with lehthyophorha of Lilljeborg, and that Centropages typicus (Kroyer), 
Boeck, 1. c. p. 19, from Norway, is synonymous with lehthyophorha denti- 
18G5. [vol. II.] 2 A
