off Head Harbor, 77 fathoms, mud and stones ; and found rarely at 

 low-water mark, under stones. Le Have Bank !, 45 fathoms, gravel 

 and stones, 1872, — one specimen with two of ^. securifrons. Off 

 Cape Negro !, Nova Scotia, 56 fathoms, large stones, 1877. Halifax !, 

 Nova Scotia, 1877; 16 fathoms, stones, sand and red algae; and off 

 Halifax!, 42 fathoms, fine sand; 52 fathoms, fine sand, mud and 

 rocks, abundant; and 57 fathoms, mud and stones. Gulf of St. 

 Lawrence !, " common on stony ground at moderate depths" 

 (Whiteaves). Labrador ! (Packard). Greenland (Kroyer, et al.). 

 Grinnell Land, and as far north as latitude Si"" 44' (Miers). Bering 

 Straits (Stimpson). Spitzbergen (Kroyer). Coast of Norway ! (G. O. 

 Sars) and of Scotland (Sowerby, Leach, et al.). This is by far the 

 most abundant species of the genus on the New England coast. 



Females carrying eggs were taken off" Cape Ann, October 17; in 

 the Bay of Fundy, at Eastport, in September or October, 1864, and, 

 by Messrs. Merriam and Wilson, in April, 1876; one specimen off" 

 Halifax, Nova Scotia, September 5, and many September 21 and 27. 

 I have seen no specimens taken in winter, but the period of carrying 

 eggs undoubtedly extends from October to April or May. 



In life this species is usually translucent and thickly mottled and 

 spotted with bright red, brownish red and white, the flagella of the 

 antennae, the thoracic legs and the caudal appendages being annu- 

 lated or banded with bright red. In some specimens the brownish 

 red predominates and the animal is less translucent. There are other 

 individuals in which larger or smaller portions of the cephalothorax 

 are opaque white, these markings sometimes extending on to the 

 abdomen or even upon the cephalothoracic appendages, but they are 

 seldom regularly disposed and are sometimes quite unlike on the two 

 sides of the same animal. Stimpson mentions bluish markings also, 

 and says the antennal scales are usually blue, but I have never 

 noticed such coloration.
