CORYNHLE. 



ledge of this species, which he has described under the 

 name of Syncoryna pusiUa. It has no claim, however, 

 to be identified with the original C. pusUIa of Gaertner, 

 and I have therefore renamed it after its distinguished 

 discoverer. 



Van Beneden describes the tentacles as disposed in 

 three equidistant rows of four each, but remarks that he 

 had seen individuals with only two rows, and that iu other 

 cases it was difficult to recognize any regularity in their 

 disposition. The number of arms is dependent on age, 

 and in adult polypites reaches 16 or even more. There 

 is a very slight tendency to verticillate arrangement. 



The stems are extremely delicate and irregularly flexu- 

 ous, and the polypary is thin and transparent. The num- 

 ber of short ramuli not bearing polypites is a marked 

 character. 



The polypites are somewhat clavate in form, blunt, and 

 rounded at the oral extremity, and tapering off slightly 

 below, but not produced as in Syncoryne Sarsii. There 

 is a small membranous dilatation of the polypary round 

 their base. 



Van Beneden has given us an account of the mode of 

 reproduction. The embryo is actiniform, and on issuing 

 from the reproductive sac resembles a miniature Octopus,
