A glance at the skeleton is sufficient to enable one to distinguish the genus. With another species of Comatula, in 450 fathoms, Pourtales dredged off Cojima two mutilated specimens belonging to a type. Fig. 418. — Actinometra pulchella. ^. of singular interest. This new Comatula may be considered as a permanent larval form; and it is not a little singular to find larval characters persisting in recent Comatulse. For this re- markable combination Carpenter has established a new genus, which he proposes to call Atelecrinus. (See Fig. 416.) In conclusion, I may mention that many of the Comatulse ex- amined were the hosts of Myzostomidae. These curious para- sites have been fully described by Dr. von Graff, from the ma- terial of the " Challenger " and " ; I give here figures.
