100 Mr. Montagu's Description of several Marine Animals 



being smaller, more slender, and differing in colour and habits, 

 it may readily be distinguished from it by the superior antenna? 

 being the longest; and from C. Locusta by the same mark, and 

 by the short upper caudal fins or appendages, as well as by 

 being destitute of the spines on the last joints of the tail. 



Cancer Gammarus falcatus. 

 Tab. V. Fig. 2. 



Body slender, with twelve smooth compressed joints nearly 

 destitute of gloss : antennae four, ciliated with hair beneath ; 

 the lower pair extremely large, and nearly as long as the body : 

 eyes small : arms four ; hands of the hinder pair very large, ob- 

 long, and sub-chelate, furnished with two spines on the inner 

 edge ; fangs falciform, with one tooth ; the fore pair of arms 

 and hands extremely small, scarcely visible by a common pocket 

 lens, and might be considered as palpi, were it not for their situa- 

 tion : legs ten, hirsute, the two anterior pairs very short, slender, 

 and usually drawn up and concealed by the plates of the body : 

 the other legs moderately large ; thighs broad and flat : caudal 

 fins three pairs, subulate. 



Length five lines. 



Colour crimson, or mottled with a mixture of white ; antennas 



marked the same. > 



This curious and rare species inhabits the deep, amongst Ser- 

 tularia, and Alga, and has only been taken by dredging at Tor- 

 cross. 



Phalangium spinosum. 

 Tab. V. Pig. 7-
