ITS TENTACLES. 259 



dense at the very extremity, where it quite fills the 

 interior. At the extreme point are fixed four tentacles 

 of the usual form, directed to the cardinal points, 

 they are long, slender, and furnished with globular 

 heads. The number was four, neither more nor fewer, 

 in every head on the zoophyte, as also in each head 

 of another specimen near. Near the lower part of the 

 polype-head, viz. at about one- third from its com- 

 mencement, four tentacles project in the same manner, 

 exactly similar to the terminal ones, but without dilat- 

 ed heads. I had thought, in examining a similar 

 phenomenon in Coryne Cerbei-us^ that these were 

 tentacles from which the heads had sloughed; but 

 their appearance in this animal is too healthy to 

 allow me to maintain that opinion; and the con- 

 stancy of their number and position in every example 

 induces me to conclude them normal. Are they male 

 tentacles as described by M. Loven in Cory fie Sarsii ? 

 Both these and the capitate ones are seen on close 

 examination to be studded with tubercles, somewhat 

 whorled, from which short bristles project at right 

 angles. (See figs. 4, 5). The inferior tentacles are 

 furnished with rounded extremities, somewhat globose, 

 but not larger than the diameter of the tentacles 

 themselves. 



The form of the polype reminds one of a familiar 

 kind of turnstile, or of those presses the screw of 

 which carries arms loaded at their extremities with 

 globes of metal to increase their impetus when turned. 

 It seems more closely allied to C. Cerberus than to 

 the other species that I have met with, though differ- 

 ing in the ramified habit, and in the number of its
