example was noted of a form which seems to be referable to the genus 
Stephanopyxis, and there were also two other species, which probably 
from lack of the necessary literature, it was not possible to identify. 
Like the Diatoms, the Dinoflagellates were also well represented 
as far as variety was concerned, although none of the species occurred 
in any special abundance. The commonest form was Prorocentrum 
micans Ehr. and others observed were Dinophysis norvegica C. and L, 
D. laevis, C and L, with the cytoplasm packed with highly refractive 
spherical globules, Peridinium divergens, and a form which seems to be 
closely related to, if not identical with Bergh’s Protoperidinium 
pellucidum. Ceratium fusus was not uncommon, and a single example 
of C. tripos was seen, belonging to a variety in which the posterior 
horns are very short and directed almost straight outwards, without 
any noticeable curvature. 
Of higher forms, mention may be made of an Anthomedusan 
that was present in considerable numbers, and represents a hitherto 
unknown species. A description of it has been drawn up by Dr. 
H. B. Bigelow and will appear as a separate contribution in these 
Proceedings. 
The crustacea were less abundantly represented than in the col- 
lection from Esperanza Inlet, but two forms of Cladocera were again 
present, Evadne nordmanni and a Podon, which in this case, however, 
was P. leuckartu. Of the Copepoda, the most abundant form was 
again Acartia longiremis, but it is interesting to note that a few in- 
dividuals of Calanus finmarchicus (Gunner) Boeck were also observed. 
Paracalanus parvus Claus was represented by numerous examples 
and occasional individuals of Centropages hamatus, Corycaeus affinis 
and a form which apparently represents a new genus and species 
belonging to the family Pontellidae. 
Paralabidocera n. g. 
Cephalic region provided with lateral hooks and with two strong 
triangular rostral processes. Dorsal eyes well developed, each with a 
single cuticular lens, somewhat larger in the male than in the female. 
Ventral eye present, but destitute of a cuticular lens. Last thoracic 
segment not fused with the preceding one, its lateral lobes hardly 
pointed in the female, but markedly so on the right side in the male. 
Abdominal region consisting of three segments in the female and four 
in the male, the genital segment being only very slightly asymmetrical, 
as are also the furcal rami in the male. Anterior antenne reaching 
to beyond the last thoracic segment, 25-jointed, several of the joints 
being, however, fused in the female so that the total number cannot
