species in the point of junction in the pali of the second and 
third cycles not being exsert, and in the V, or A, not being so 
prominent ; and, further, in the coste being covered with fine, 
sharp granulations, while in J). /talicus they are “composed of 
series of very regular granules.” ‘The columella is also less de- 
veloped in the recent than it is in the fossil form. All these 
characters are minute, and may depend, to a certain extent, 
upon the condition of the specimens; but it seems to be best, 
on the whole, to retain the name given by M. de Pourtales for 
the present. 
A surveying party, sounding from a boat in 200 fathoms 
off Bermudas, brought up in the cup-lead a very beautiful spec- 
imen of a variety of this species described by Count Pourtales, 
in which the primary coste are large, and prolonged beyond 
the margin of the calicle. Pourtales’ specimen was imperfect ; 
ours was finely preserved, and the horn-like appendages were 
developed to a remarkable degree. The diameter of the calicle 
is 9 mm.; the length of the horns 3-5 mm., or more than one- 
third the diameter of the calicle; they are slender and rounded, 
and they taper to a fine point. A smaller horn is developed 
in relation with one of the secondary coste, but the remaining 
secondary costze show no tendency to elongation. The horned 
or stellate variety of D. Agassizii appeared at first to Pour- 
tales to present good specific characters, but the examination 
of intermediate forms showed that it could not be regarded as 
specifically distinct. Our Bermudas specimen, which is in most 
excellent preservation, shows some other points of interest: the 
pali, as a whole, project more prominently above the general 
elevation of the septa than they do in the unarmed variety, 
and the A formed by the junction of the secondary with the 
tertiary pali is prominent and conspicuous, in this respect ap- 
proaching the fossil species, D). /talicus. 
Among the Oculinidze, we obtained from both localities 
abundant examples of Lophohelia Carolina, Pourrates. A
