POLYPS AND CORALS. 329 



rows, about twenty-four in each row. Disk narrow ; 

 mouth everted. Toward the base of the column there 

 are, in the only specimen seen, smooth, yellow, spherical, 

 ova-like bodies, embedded in circular cavities formed in 

 the epidermis and true wall, which are partially open 

 outwardly so as to expose a small portion of the enclosed 

 body, Avhich can be easily removed by enlarging the open- 

 ing of the cavities. These are arranged pretty regularly 

 in quincunx in four transverse rows all around the lower 

 third of the column, and rather distant. They are about 

 .5 of an inch in diameter, and their nature is quite uncer- 

 tain. Possibly they are the eggs of some parasite. Height, 

 in alcohol, .7 of an inch; diameter of base, .45; of 

 disk, .20. 



Arctic Ocean, north of Behring's Straits, in thirty 

 fathoms. Capt. John Rodgers. 



The above description has been made from a specimen 

 beautifully preserved in alcohol, with the disk and tenta- 

 cles expanded. The column is doubtless much contracted, 

 especially in length. 



In addition to those enumerated above, the following 

 species belong to this genus.

In addition to these there are several undescribed spe- 

 cies found at Panama and vicinity. 



The genus Capneopsis Duch. and Mich., Supl. p. 128, 

 is evidently closely allied. The only species, C. Solidago, 

 lives buried in sand to the tentacles.
