Dr. Clarke did find a number of this same species tunhling about in the

surf when he went ashore collecting micros the evening of April 11. 
Therefore, they surely were about on the Intervening days, but as we 
were severally and otherwise busy, the swarming between the 12th and 
14th must have escaped our notice. The swarming petered out on the 15th 
of the month. 
As surprising as the Linuche swarm on the 14 th was the presence 
in the same day, as far as we could make out, of three and three only, 
specimens of a delicately pastel-tinted purple, 8-tentacled jellyfish 
with a "bell’ 1 about l| inches high and nearly 2 inches in diameter— 
Pelagia cyanella . This is likewise a tropic-sea form, known from around 
the world, and also said to swam at times in considerable numbers . In 
this species the development is direct. The fertilized egg develops 
into a free-swimming larval form, the planula, which grows to become a 
mature Pelagia in turn.

Still another Ascension Bay surprise was turned up by our indefatigable 
Dr* Clarke. With his setup for collecting flying insects at night— 
an expense of white sheeting illuminated by two strong Coleman lights— 
he captured a single specimen of a micro found previously only in the

(Fig. ) may be just about as widely distributed as the palmettoes.
