Schizopoda, &c.)

Tunicata (Appendicularia, Salpa.) 
Vertebrata (Fish ova and embryos.) 
There is apparently a considerable difference both in 
the numbers and the kinds of animals in the different 
bottles, some of the groups being evidently more abundant 
at certain times than at others. | 
This collection, from its extent and the care with which 
it has been made, will supply particularly favourable q 
material for working out the distribution of the more — 
important groups of surface animals in the neighbourhood 
of Malta. Mr. I.C. Thompson has already commenced 
the examination of the Copepoda, and it is hoped that 
other specialists will be found who are willing to separate 
out and identify the remaining groups.
