pools oil the rocky platform of the reef, and in caverns 

 along the reef-rim. During the day it hides in cavities ; 

 at night it creeps about over the rocks of the bottom. 

 The natives are very foud of the flesh, which they prepare 

 for food in a variety of forms. Dried "squid" is com- 

 mon in the fish-markets. Our cuttlefish is rarely more 

 than 18-26 inches in length. The true "devil-fish" of 

 many a sea-tale is a giant squid, Architeuthis, which in- 

 habits the Newfoundland banks and often attains the gi- 

 gantic proportions of an over-all length of 50 ft., with a 

 body 6 by 9 ft,, and enormous arms 40 ft. long. 



Our reefs support a characteristic crustacean fauna. 

 In the growing coral at the reef-edge are found a number 

 of small Cyclometopous crabs, which are often beauti- 

 fully sculptured and colored to harmonize with the coral. 

 The Alphehhc, which are shrimp-like Macrura with highly 

 asymmetrical claws, are commonly found in pools on the 

 reef. In the coral rubble formed by the disintegration 

 of the reef-rim, in relatively shallow water, numerous 

 Leucosiid crabs are found. Many lowly forms of Ento- 

 mostraca are abundant, but have never been surveyed
