CHAPTER V. 



MISCELLANEOUS COLLECTIONS. 



Section I. Ckustacea. — Many crabs are found 

 under stones, logs, etc., in the South. Some in- 

 habit holes on the shore or in the woods, and a few 

 climb trees. Some can only be obtained by dredging 

 in deep water, while others always inhabit the shallow 

 margins of bays, etc. Many interesting species are 

 found clinging to seaweed picked up floating in deep 

 water, while others are taken from the shells of living 

 Mollusks. A few species occur in fresh water far from 

 the sea, and at least one has been taken from the 

 caves of Kentucky. 



A good way to preserve the smaller species is, to 

 stitch them to cardboard. In transporting Crusta- 

 ceans, they may be packed in salt; then, afterwards, 

 washed and dried. 



COLLECTING MOLLUSKS. 



SoLiGiNiD^ AND SoLiGOPSiD^ Squid and Cuttle- 

 fishes, may be found floating in the open ocean, or 

 drifted ashore on beaches. They may be taken in nets, 

 or by di-edging. They should be preserved in alco- 

 hol, or casts taken of them. 



Pholadid^, Boring-Shells. — The species of Teredo 

 and Xylotrya are found in timber that has been be- 

 neath the surface of the water for some time. Some 

 of them should be preserved in alcohol, and the shells 

 of others saved, care being taken to keep the parts of 

 individual shells together. Members of Pholus and
