COLE: PYCNOGONIDA COLLECTED AT BERMUDA. 
327 
small branch of Obelia marginata Allman, in which it will be 
observed that the general color plan is very similar to that of the 
pycnogonid. This protective resemblance is heightened by the 
slenderness of the legs and body, which are of nearly the same 
diameter as the branches of the hydroids. The combination of 
form and color in this subspecies makes the animals very incon¬ 
spicuous, and in order to find them it is necessary to look the 
hydroids over piece by piece with great care. Some idea of the 
protection thus afforded is given in figure 3 (pi. 20) where a pyc¬ 
nogonid is shown clinging to the hydroids, both being drawn 
natural size. 
One male was found carrying eggs. These were in nearly a 
dozen small, irregularly rounded masses. The eggs themselves are 
very small, so that there are large numbers of them in a single mass. 
As is shown in the table below, only four specimens were found, 
all males, and all came from the ‘cut’ connecting Harrington 
Sound with Flatts Inlet. The single specimen of A. insignis taken 
by the ‘Challenger’ was dredged at Bahia (Brazil) in 7 to 20 
fathoms of water.
