This species is very near the last, if not identical, which is quite 

 probable. The principal diiferences are in color and, apparently, in 

 the number and length of the tentacles, which appear to be longer 

 and fewer in this form. 



Several other undescribed species of Sagartia are known to occur 

 on different parts of the coast. One species from Panama is remark- 

 able for the thinness and transparency of its walls when preserved in 

 alcohol. It grows to a considerable size, some of the preserved spe- 

 cimens being 1*5 inches high and 1 in diameter. 



Other species were collected at the Gulf of Georgia and well figured 

 by Mr. A. Agassiz, several years ago.

Margin of the disk, outside of the bases of the tentacles, surrounded 

 by a single circle of bright colored, rounded tubercles. Acontia long 

 and slender, protruded from the mouth, and^eMajos from lateral pores. 



The authors of this genus give as one of its characters " pores situ- 

 ated near tlie border of the disk,"— a character Avliicli may possibly 

 exist, but of which there is no proof. In Drayton's figures acontia 

 are represented as protruding from the mouth, which, if carelessly ob- 

 served, might appear to be figured as coming from the sides, but in 

 the description oi A. pnmula we find it stated that " the threads pass-
