Natural History, and last, but not least. The Sea-beach at 

 Ebb-tide, by Augusta Foote Arnold, that so-called * popular' 

 work which belies its critics by being so well thumbed in all 

 laboratories. 



After a summer's spotting of the territory with a hand 

 dredge, I organized the Survey and started work in the spring 

 of 1926 and have continued the work each year, from the last 

 week in June until the first week in September, up to the pres- 

 ent time. It has been my aim to publish the results as the 

 work progressed and there have already been issued the fol- 

 lowing parts : 



Part 1. INSECTA— The insect fauna, with reference to the 

 flora and other biological features, by Charles Willison John- 

 son, Boston Society of Natural History. 247 pages, 1 portrait. 



Part 2. FISHES— A contribution to the life-history of the 

 angler (Lophius piscatorius), by members of the Survey 

 Staff. 30 pages, 5 heliotype plates, 3 maps. 



Part 3. CRUSTACEA— New Crustacea from the Mount 

 Desert Region, by Charles H. Blake, Massachusetts Institute 

 of Technology. 34 pages, 15 text figures. 



Part 4. VERMES — Three new species of worms belong- 

 ing to the Order Echinodera, by Charles H. Blake, Massa- 

 chusetts Institute of Technology. 34 pages, 8 text figures. 



This volume covers the following forms. In it have been 

 bound Parts 2, 3, and 4 which were originally issued in pam- 

 phlet form.
