Die erste Beschreibung dieser vom Dampfer ‘‘ Bibb” 1869 in der Tiefe von 
450 Faden an der Kiiste von Cuba gefischten Species wurde von Pourtalés ge- 
geben. Sie lautet folgendermaassen: 
“Ten arms; mouth central. Centrodorsal plate conical, covered with cirrhi nearly to the tip. 
Cirrhi very long and slender of 28 cylindrical joints. First radial concealed by the centrodorsal 
plate, second very short; axial radial pentagonal or shield-shaped. First brachials very short. 
Arm-joints with imbricated, serrated edges; five to seven forming a syzygium. First pinnule not 
much longer than the second, the others rather short and slender, consisting of about ten joints, 
and increasing in length towards the end of the arm. 
Two specimens in 450 fathoms on the coast of Cuba. It resembles somewhat A. Sarsii, but 
differs from it by its flatter centrodorsal plate, and by an entirely different shape in the Ist and 
2d brachial, particularly the second, which has not the projection into the first brachial, like A. 
Sarsii.”’ — (Bull. Mus. Comp. Zodl., 1, No. 11, p. 356). 
Unter gleichem Namen wurden 9 Jahre spiter zwei vom ‘‘ Blake” gefangene 
Comatuliden beschrieben, welche Pourtalés vorliufig der Species A. cubensis zu- 
theilte, die jedoch mit dieser nichts zu thun haben. Des Interesses halber fiihren 
wir die Beschreibung vollstindig an: 
_ “To this species I refer provisionally two specimens very much mutilated, having lost the 
cirrhi and the arms, differing somewhat from my type specimen, but possibly the differences may 
be due to age. The centrodorsal piece is long conical or rather acorn-shaped, 5mm. high by 33 in 
diameter; it has ten vertical rows of horseshoe-shaped sockets for the cirrhi, 5 or 6 to a row, alter- 
nate on contiguous rows. It shows in the upper part ridges, corresponding to the interambulacral 
spaces. Cirrhi with long compressed joints. First radials projecting beyond the edge of the 
centrodorsal piece. Second radials smooth and but little shorter than broad (in the type of my 
A. cubensis the first radials are not visible and the second quite short). Axial rhombic. First 
brachials well separated from one another. Syzygium in the third joint, afterwards four joints 
between two syzygia. Mouth excentric; anus central and tubular. 
Station No. 43, Lat. 24° 8’ N., Long. 82° 51’ W: 339fms. A smaller equally mutilated speci- 
men had been dredged by myself formerly in 450 fathoms near Havanna.’’— (Bull. Mus. Comp. 
Zodl., 5, No. 9, p. 214, 215). 
An dieser Beschreibung fillt gegeniiber der ersten besonders die Angabe der 
; excentrischen Lage des Mundes auf. Bei aufmerksamer Vergleichung der bei- 
_ den eben citirten Beschreibungen von Pourtalés gewinnt man bald den Ein- 
_ druck, dass es sich dabei um ganz verschiedenartige Exemplare handelt, welche 
-Pourtalés unter einen Species-Begriff zu bringen suchte.
