70 Scientific Intelligence. 
From near the sides of the axial edge, the polyp-rows start, and 
run obliquely upward to the opposite side, where they nearly 
meet, presenting, when that side 1s observed from above, a concen- 
tric chevron or A-like arrangement, modified by the convexity of 
the polypidom. The more conspicuous polyp-rows show from nine 
to fourteen polyps, with occasional intermediate rows of three or 
more 
The sath of the most perfect of Dr. Blake’s specimens was 
siaty-six inches ; ; of which, commencing at the tip, a length of 
forty-eight and a quarter inches was occupied by the polyp-rows, 
which numbered two hundred and forty-five, or twice that a 
when a sides or arms of the chevron or A are considered. 
number of polyps in each row was, in this specimen, from eight “ 
eleve gh occasional intermediate shorter rows of from three to 
seven. Estimating ten to the row, this specimen exhibited about 
Jive thousand polyps, = of ud oe as well as the polyps in the 
other specimens, were filled with ova, of an orange color. In the 
row and the swell of the base or root, is eleven and one quarter 
inches ; thence to the termination of the base, six inches. 
e average dimensions of thirty-six of the axes in the Museum 
of the California Academy is five feet six and one-third inches in 
length, and the diameter. of the largest, nine thirty-seconds of an 
inch; diameter of smallest specimen, one-sixteenth of an inc 
r, Blake’s Specimens were preserved in a ietiare of glycerine 
and alcohol; and the more delicate tissue of the polyps appears to 
have been somewhat injured by the latter ingredient. 
Additional specimens of the above species, fro - the same local- 
ity, have been pice from J.S. Lawson, Esq., of the U. 8. Coast 
Survey, by George Davidson, Esq., President of the Ac ademy. 
These latter were put in glycerine only, and are in better condi- 
tion ere those received by Dr. Blake. 
e specimens received from Mr. Lawson, some individuals 
are Danae than either of Dr. Blake’s. In these the poly p-rows 
e farther apart, ad there are not so many polyps in the row; 
opposite the axial edge, the polyps being not nearly so many i 
the same length, or presenting (as do some ot Dr, Blake’s speci- 
rangularis from Bice pe: in Zaye species, the rows of polyps, it 
is stated, are ope a of “four, five or six polyps in a row,” one

most nearly allied to the Halipteris ee and Dan., sp.) and
