390 ANTEDON. 



visible, so that the axial radial appears almost sessile. The radials of two contiguous arms, and 

 the first brachials of the same pair well separated down to the angle. Arms convex on dorsal 

 side. Syzygia composed of three or seldom four articulations, with very oblique joints, and very 

 finely denticulated edges, better recognized by the touch than by the eye. The first three or 

 four pinnules of the arms long and nearly equal, the pinnules of the middle of the arm shorter than 

 those of the base or extremity. Arms about three inches long. Color pale greenish, turning 

 white in alcohol. All the specimens had the pinnules filled with eggs. Quite abundant in 100 

 fathoms off Sand Key." — (Bull. Mus. Comp. Zool., 5, No. 6, p. 111). 



Das Material, welches dieser Beschreibung zu Grunde liegt, stammt, wie 

 schon bemerkt wurde, von der kurzen Fahrt des U. S. Coast Survey Steamer 

 "Corwin" im Jahre 1867, "May 17, Pos. 1, 90-100fms., 5m. S. S. W. of Sand 

 Key, Fla." ' Pourtales haben viele Exemplare vorgelegen, wie aus der eben 

 citirten Beschreibung hervorgeht; schon oben wurde erwahnt, dass das einzige 

 uns vorliegende Exemplar vermuthlich — es spricht hierfiir der Fundort und 

 das Fehlen einer "Blake" Etiquette — eins der von Pourtales gefischten Exem- 

 plare ist. 



Eine kurze Beschreibung gab Pourtales im folgenden Jahre (1869): 



"A. hageni Pourt. (Comatula hageni Pourt., Bull. Mus. Comp. Zool). This species ap- 

 proaches nearer A. rosacea than any of the other species found in this region; it differs, however, 

 in some important parts, such as the form of the centrodorsal plate, of the ovaries, of the joints 

 of the cirrhi, etc. The arms are rounded, more flexible, and can be coiled entirely over the back. 



Found from 94 to 195 fathoms."

 Gulf Stream Expeditions, in 1S67, 1868, 1S69, Bull. Mus. Comp. Zool., 1, p. 355). 



Ueber das spiiter vom "Blake" gesammelte Material schrieb Pourtales: 



"A. hageni Pourt. The young are marked with dark brown spots arranged in pairs on the 

 beginning of the arms, but becoming confluent towards the end. In the adult the spots are hardly 

 apparent.

Sehr wichtig, besonders in kritischer Hinsicht, sind die Ausfuhrungen P. H. 

 Carpenters, welchem ein grosses Material, offenbar das den eben citirten Be- 

 schreibungen von Pourtales zu Grunde liegende, zu Gebote stand, wahrend wir 

 selbst nach seinem Tode, wie schon erwahnt, nur ein einziges Exemplar erhiel- 

 ten. Die Bemerkungen P. H. Carpenters in seinem "Preliminary Report" 

 lauten: 



"Of all the Antedon species dredged by the U. S. Coast Survey, that with the widest range 

 within the Caribbean Sea is the little ten-armed A. hageni Pourt. It was obtained by the "Blake" 

 on the Yucatan Bank, and also at various stations between Dominica and I Irenada, at different 

 depths between 75 and 291 fathoms; while Mr. Pourtales dredged it in great abundance at several
