grow up to maturity the next April, then to repeat the cycle. 
I do not know if Linuche swarms every year, but this Ascension 
Bay swarm is the first I have ever witnessed, though I have 
cruised the Caribbean several Aprils in succession. Though they 
were reported most widely distributed in tropic seas, the only 
specimens in the Museum heretofore were from off the coasts of 
Cuba, the Bahamas, and Florida, drifting in the Gulf Stream.

Of equal interest was the /occurrence on the same day of 
three specimens of a delicately pas tel- tinted purple, 8-tentacled 
jellyfish with a "bell" about 1-1/2 inches high and nearly 2 inches 
in diameter--Pelagia cyanella. This is likewise a tropic-sea 
r 
form, known from around the world, and also said to swarm 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 set-up for collecting flying 
insects at night (an expanse of white sheeting illuminated by 
two strong Coleman lights) he captured a single specimen of a 
micro found previously only in the southern States, where it is 
not uncommon and where its larvae feed on palmettoes. The larval 
habit is undoubtedly the same here, for palmettoes are also 
common in YucatAn. In the American tropics this bizarre-looking 
moth (Fig. ) is probably as widely distributed as the palmettoes. 
Collecting on land also has its hazards. Shortly after his 
first few trips ashore at Ascension Bay, Dr. Clarke developed 
the most severe case of "poison ivy." This time he was having
