Distribution: — „Die „V a
1-d i v i a“ fischte diese Art zwischen
dem 26° s. Br. und dem 37° s. Br. und
außerdem einmal unter 31° n. Br. Auch nach den Gauß- Fängen scheint die Art in einer
breiten äquatorialen Zone zu fehlen. Atlantischer, Indischer Ozean“ (G. W. Müller, 1908, p. 70).
The finds mentioned above seem scarcely to support this idea. Probably this species is
distributed all over the central part of the Atlantic Ocean.
Bispinosa group G. W. Müller.
According to G. W. MULLER this group comprises, in addition to the forms dealt
with below. three other species, namely C. striola G. \Y. MULLER, C. atlantica (J. LUBBOCK)
and C. orthotricliota G. W. MULLER. To these may be added the forms included by this writer
as synonyms of C. bispinosa, namely C. secernenda V. VÅVRA and C. Mülleri Oh. JUDAY.
Of these species C. Haddoni, C. bispinosa and C. striola are, as G. W. MULLER has pointed
out, certainly very closely related to one another. It is difficult to sayanvthing certain as to the
systematic position of C. secernenda and C. Mülleri (cf. pp. 674, 675 below), but at any rate
they are very close to the three species just mentioned.
On the other hånd C. atlantica and C. orthotrichota are, according to G. W . MULLER,
more isolated; it is less certain that they belong to this group. I was unfortunately unable
to investigate material of these species, so that it is not possible for me to give any further
opinion in this question.
