148 THE ZOOLOGIST. 



to see many of this species, and who probably never examined 

 one alive, writes, "Colour light buff?" As this is the tint of a 

 much dried and bleached specimen, he evidently felt the 

 necessity for making this statement in doubt. He also states 

 that the length of Leach's specimens is rather more than half 

 an inch, whereas, judging from the number of specimens that 

 have passed through my hands, I should say that the length of 

 the mature animal, from the tip of the rostrum to the tip of the 

 tail-plate, was nearer an inch. 



The usual habitat of this species is under little stones or bits 

 of shell that have collected in the hollows often formed under 

 some large boulder ; but, so far as I have been able to ascertain, 

 it is never found upon a sandy or muddy bottom. Favourite 

 spots may be seen among the low-tide pools of St. Clement's 

 Bay, or Grouville Bay, Jersey ; and here, with a little careful 

 search, may be found this uncommon crustacean, at times in 

 considerable numbers. Mr. Sinel informs me that he has taken 

 it with ova from -January to September. 



Bell states that this species was discovered by Montagu and 

 sent to Dr. Leach, who asserts that it occurs in rock-pools left 

 by the tide on the Devon and Cornwall coasts. It has also been 

 recorded from Galway, from "the coast of France," and from 

 the Adriatic Sea. 



Hippolyte spinus, Sowerby. 



This is a genus about which I can say but little, since I have 

 unfortunately had very little opportunity of seeing many speci- 

 mens of it. There are moreover a few species described in 

 various reports, &c., which were evidently unknown to Bell 

 when he published his work on the Stalk-eyed Crustacea, and 

 his genus has since been subdivided, so that it is now difficult, 

 without further examination of specimens, to say much that 

 would be of use to the student. 



As regards this particular species, however {H. sjnnus), it 

 may be described as follows : — The general form is very robust, 

 the cephalothorax particularly so, and armed with a powerful 

 rostrum, which springs from a serrated ridge commencing at 

 the juncture with the abdominal segments. These abdominal 

 segments are humj)ed in the middle, the third segment forming 

 in its centre a strong spine, curved downwards towards the tail,
