most part in the bell-cavity of Turritopsis nutricula, from whose 

 stomach it appears to derive its nourishment until it is prepared to 

 pursue an independent existence. 



The coloration of this species is a rich and rather reddish orange 

 on the sexual lobes, with deep lake in the furrows; the labial ap- 

 pendages frosted, as well as to a slight extent the outer surface of 

 the disk; tentacula have sometimes a purplish ^int, with a slight 

 nucleus of lake in the clavate extremity. Found in Charleston 

 Harbor from the early part of June to the early part of October. 



SAPHENIA. Eschscholtz, (Forbes,) 



General form varying from one having a profile emarginate on 

 each side near the summit, to that of a hand-bell, in which the 

 emargination has proceeded so far, as to make the upper part of 

 the disk appear a more or less conical appendage to the lower 

 The sexual glands are placed on the upper part of the digestive 

 trunk, the two-fold character of each gland being quite distinct. 

 To this part of the trunk the stomach proper seems also confined. 

 The neck, which like the neck of a bottle, separates this upper 

 portion from the mouth in all the genera of the group, is in Saphe- 

 nia very long, and in the following species when contracted ap- 

 pears capable of forming a separate or lower cavity, PL 8, fig. 3 a. 

 The circulatory canals are broad as usual in the group. Only 

 two of the radiate canals have corresponding tentacula, and these 

 two at their junction with the marginal canal form a sort of flat 

 triangular sinus. The somewhat fusiform bulbs are proportion- 

 ally large, and the characteristic of the tentacula are length and 

 great contractility. There are no ocelli. Larva — unknown. 



Remark. It may be reasonably questioned whether this genus 

 is really that to which Eschscholtz intended to give the name 

 Saphenia. Not having within reach the material for settling the 

 doubt, I have continued to use Saphenia in Forbes' sense. 



Distribution, (with the present limits of the genus.) British 

 seas, Mediterranean and Charleston Harbor.

Bell shallow, being almost square in profile ; bell-wall thin 

 throughout, and surmounted above with a long conical appendage 

 tapering to a delicate point, which is sometimes turned jauntily 

 on one side as in the figure. Digestive trunk very long, when
