Hydra tentaculis denudatis, numerofiftimis ; cor- 
pore longitudinaliter fulcato. 
The natural fiz e of this animal, grown to its full 
age, is reprefented in the firft figure, lit. A, fhows 
the animal lufpended in the air, and lit. B, is the 
fame whilft under water. The body of this polype 
is of a light chefnut colour, and feels perfectly 
fmooth, though it be lengthways fulcated by a num- 
ber of fulci, that are frequently divided into three 
fmaller ones, and are continued into the dentated 
margin, that furrounds the upper periphery of the 
body, juft beneath the infertion of the feelers. Thefe 
feelers, riling from the difk of the polype, are, ac- 
cording to the age of the animal, between 120 and 
200 in number j they exceed the body, when ex- 
panded, by more than an inch in length, and are of 
a beautiful fea-green colour, except towards their 
extremities, which are coloured with a lively red, 
like that of the rofe. The difk is of the fame brown 
colour with the reft of the bodv, and contains in its 
center the mouth of the animal, which is an aperture 
of various fhape and diameter. 
The two varieties of this fpecies, which I met with, 
differ but little from the already defcribed animal. The 
feelers of the one, inftead of being green, are through- 
out of a red colour, like that of the mahogony wood. 
The other variety has pale afti-coloured feelers, 
marked with a fmall white line running along their 
back; its body is of the fame chefnut colour with 
that of the firft fpecies ; but the fulci are not divided, 
nor has it a dentated margin furr'ounding its upper 
periphery.
