Thus all the invertebrated animals, which are technically di- 

 vided into eleven groups, are here put into three, and the verte- 

 brated animals which technically comprise only one group, are 

 here for easier understanding, divided into four.- 



In this division we must remember that there is much over- 

 lapping of forms, especially in the water-inhabiting inverte- 

 brates, for a single zoological group may contain some species 

 living in fresh water, and others which are strictly marine. 



What progress has been made in the study of what our state 

 affords in these several groups? Remembering that several of 

 these groups contain, thousands of species, my hearers will ex- 

 cuse me if I fail to discuss all the groups in full detail. 



I. MARINE INVERTEBRATES 



This group includes thousands of small, little-known forms 

 of life, along with a host of larger and better-known forms. Such 

 work as has been done in listing and making known our species 

 has been chiefly at the government Biological Laboratory at 

 Beaufort where there are special facilities for work. Dr. H. V. 

 Wilson, of the State University, informs me that the sub-groups 

 of this group which are best known from the systematic stand- 

 point are: 



The Coelenterates (Jelly-fishes, Sea-anemones, Corals, etc.) 



Echinoderms (Star-fishes, Sea-urchins, Brittle-stars, Feath- 

 er-stars, Sea-cucumbers.) 

 Crustacea (Crabs, Lobsters, Shrimp, etc.) 

 Mollusca (Bivalved shells, Conchs, snails, etc.) 



Dr. Wilson informs me that the larger forms of Crustacea 

 will be thoroughly listed in a paper soon to be published by Dr. 

 Hay, of Washington, and Dr. Shore, of Raleigh. This list in- 

 cludes parts of several of the most important zoological groups, 

 but leaves the whole group of one-celled animals largely unex-
