I. METHODS OF COLLECTING AND PRESERVING 



CRUSTACEA 



IT may be useful to give here a few hints as to the 

 methods of collecting Crustacea. Of the species 

 that live in the sea, many may be found between tide- 

 marks by turning over stones and searching among 

 sea-weeds and in rock crevices. A small hand-net, 

 made by fastening a bag of coarse muslin to a stout 

 wire ring of a few inches diameter, is useful for fishing 

 in rock pools. Shore-collecting in this manner is 

 most productive at spring-tides, when the deeper 

 levels of the shore are open to exploration. 



Many burrowing species are to be found by digging 

 in the sand near low-water mark. In addition to 

 Crabs and other large species, many minute forms, 

 Amphipods, Cumacea, and the like, inhabit such 

 localities. The best way of collecting these is to 

 stir up a spadeful of the sand in a bucket of water, 

 and, after allowing the sand to settle for a few 

 seconds, to pour off the water through a muslin bag. 

 After repeating the operation two or three times, the 

 contents of the bag are washed out into a jar or dish
