in his original description. The number of rings on the pedicel varies, those 
higher up on the stem having the shorter pedicels. 
The gonothecse, which are seen here for the first time, undoubtedly belong 
to an Obelia, a fact which therefore fixes the species in this genus. They 
are not much larger than the large hydrothece, and are borne on pedicels 
with about 5 rings each. 
Locality—Khor Shinab, 10-12 fathoms. 
CAMPANULARIA JUNCEA, Allman *. 
Small overgrown pieces only. 
Locality—Khor Dongola, 20 fathoms. 
CAMPANULARIA DENTICULATA, Clark +. (Plate 9. fig. 3.) 
The present specimens agree with Torrey’s{ description of this species 
in height, in branched stem, in the stem opposite the origin of each 
hydrothecal pedicel taking a knee-like bend, and in the pointed teeth of the 
hydrotheca. It differs in the pedicel not being always ringed throughout, 
and in the teeth of the hydrotheca being rather fewer. 
The most striking feature of the present species is the mode of branching. 
The stem rises straight to the base of the hydrothecal pedicel and then takes a 
bend, after which it rises straight again to the next hydrotheca on the 
opposite side, and this is repeated sometimes for eight or nine times with the 
occasional complication of two pedicels being given off at once, nearly 
opposite to each other or on the same side, one below the other. 
Gonothecz, previously unknown, are to be seen on these specimens. They 
are situated, usually, near the base of a hydrothecal pedicel, singly, or two 
opposite, or are, sometimes, given off from the stem. They are borne on 
short faintly ringed stalks and are very long and cylindrical with blunt 
tops (see fig. 3).
