small, about a quarter or a fifth of the anterior side of the first endopodite joint. The s i x t h
l i m b has 24 posterior ventral bristles. The s e v e n t h 1 i m b has twelve cleaning bristles,
six of which are concentrated distally, three on each side, and six scattered somewhat proximally
of the former ones, three on each side.
G. S. Brady and A. M. NORMAN’s form Asterope Mariae, 189G, p. 630, is stated to have
been taken at a number of places along the coasts of England and Scotland. The male and the
female are described. The male seems undoubtedly to belong to the Grimaldi group. The female,
on the other hånd, can only be referred to this group with a certain amount of hésitation.
F e ni a 1 e: — Shell: Eengtli 2,4 mm. The shape of the shell is the characteristic one for
the Grimaldi group. Seco n d ante n n a : The endopodite has one short bristle distally
on the second joint. M a n d i b 1 e: At the middle of the dorsal side of the second protopodite
joint there is a single bristle, which is about as long as the dorsal side of this joint. The exopodite
is about half as long as the anterior side of the first endopodite joint. The second endopodite
joint has a long narrow bristle between the main bristles b and c. Maie: — Shell: Length?
It is of the sanie type as is characteristic of this group. Mandible: The bristle situated
at the middle of the dorsal side of the second protopodite joint is like that of the female. The
exopodite is very short, only about a sixth or a seventh of the length of the anterior side of the
first endopodite joint. The second endopodite joint has no long narrow bristle between the
main bristles b and c. Sixth 1 i ni b: (With regard to this and the following limb the text
does not explain whether the descriptions are based on male or female specimens). This has
25 posterior ventral bristles. Seventh limb (according to the text, not according to
the accompanying figure): The cleaning biistles are like those in the above-mentioned form
described by G. 0. SARS.*
It seems to follow from this review of these forms, which is perhaps too much Condensed
on account of space: 1) that E. GrüBE’s species Cypridina oblonga cannot be considered as
identical with A. Grimaldi and its variety or with any of the other forms discussed here, 2) that
A. Grimaldi and its variety cannot be identified either with G. 0. Sars’ Asterope oblonga, 1887
or with A. Mariae, G. S. BRADY and A. M. NORMAN, 1896, 3) that the relation between the
two latter forms cannot be decided with certainty; at any rate the females of these species
cannot be considered as identical; the males, on the other hand, seem to be very closely related.
4) G. S. Brady’s species Cylindroleberis Mariae, 1868 b, must be considered unidentifiable.
With regard to G. W. MÜLLER’s synonymization of Copechaete elongata and C. affinis
I need only refer to the historical sketch of the genus, p. 434.
It is certain, if we are to judge from these authors’ figures, that J. A. CuSHMAN’s species
Cylindroleberis Mariae, 1906, p. 366, Cylindroleberis Mariae, Ch. JUDAY, 1907, p. 143 and
Cylindroleberis oblonga, R. W. Sharpe, 1909, p. 423. ali American fornis, cannot be considered
identical with any of the European forms dealt with above. With regard to CuSHMAN’s species
I may point out: First an ten n a of the female: The sensory bristle of the tiftli joint has no sen-
* I may perhaps mention that I wrote to Professor G. S. Brady to ask whether the type-specimen of Baird’s
species was in existence and whether he had examined 0. He answered that he did not know whether it still existed
and could not remember if he had investigated it.
