PERRIER's description has now been proved deficient as regards this point, 
his specimens likewise having three adambulacral spines on some of the plates, 
the var. Se/kirki can no longer be maintained, the said character being the 
only — supposed — difference from the typical form. I have had MEISSNER’s 
types for examination, and thus can definitely state them to be identical with 
the typical form. The figure here given 
is drawn from one of MEISSNER’s specimens. 
I beg to express here my indebted- 
ness. to Prof. HARTMEYER for his kindness 
in sending me for examination the above- 
named type specimens, as also those of 
MEISSNER’s <Asterzas fernandensis (see 
below). 
As to the geographical distribution 
of Asterina calcarata the following remarks 
may be made: 
H. L. CLARK (12) in his paper on 
Echinoderms of Peru writes: »Were it not 
that a variety (selkirki, Meissner 1896) is 
common at Juan Fernandez, one might be 
doubtful whether PERRIER’s specimens 
really came from Chile, especially as DE 
ROCHEBRUNE (1881) records calcarata from 
the Cape Verde Islands. For the present, 
however, we may retain the species in the 
Chilean fauna, with the hope that further 
collecting on the South American coast 
may settle the doubt concerning it.» — 
This question may, however, now be 
looked upon as settled; that Asterina cal- 
carata is found at Chile and Juan Fernan- 
Fig. 2. Part of ambulacral furrow of dez, and that the variety selkirki only is 
Asterina calcarata. c. 49 a synonym of Asterina calcarata itself can 
no longer be doubted. 
DE ROCHEBRUNE (6) gives the localities Saint-Vincent, and Sainte-Lucie, 
without, however, adding any description of his specimens or stating whether 
they agree with the specimens from Chile or not. It is, therefore, not possible 
from DE ROCHEBRUNE’s account alone to know for certain if it really was 
Asterina calcarata. DE ROCHEBRUNE adds »Mus. Paris», but Dr. GERMAIN 
has informed me that DE ROCHEBRUNE’s specimens of this species are not to 
be found in the Museum, and he supposes that probably they have not been 
correctly determined. These localities, accordingly, should be omitted. 
Whether A. calcarata occurs at Cap Verde is still uncertain. Since it 
has been found at Cape (KOEHLER 10) there might be some possibility of its 
occurring also at the Cape Verde Islands; only renewed researches in this 
place can settle this question.
