150 THE ZOOLOGIST. 



Hippohjtc Thompsoni, Bell. 

 This species is characterised by its describer as differing in a 

 few minor details from some of the other species. He states 

 that he saw but one specimen, and, as his figure is in general 

 details very like that of H. spinus, I think it probable that this 

 is merely a variety of that species. 



Hippolyte Prideauxiana, Leach. 



This species has been described by Bell as being like 

 H. varians, but much smaller, and of a reddish brown colour. 

 The rostrum is straight and smooth on the upper surface, and 

 the abdomen is much bent at the third segment. It has been 

 recorded from the coast of Devonshire. 



Hippolyte imndaliformis, Bell. 



Under this name Bell described two specimens which were 

 obtained from Loch Fyne. He states that it bears a remarkable 

 resemblance to Pandcdus annulicornis, but that at the same time 

 it is in all its essential characters a true Hippolyte. 



It has, I believe, been since taken in the Hebrides in 1866, 

 and in Shetland in 1868. 



Hippolyte cidtellata, Norman. 



In the British Association Keports, 1866 and 1868, this 

 species is recorded from the Minch and Shetland. 



Hip)polyte securifrons, Norman. 



In the ' Transactions of the Tyneside Naturalists' Field Club,' 

 1863, this species is noticed, and is stated to have been taken at 

 St. Andrews, Shetland, Berwick, and the Dogger Bank, It is 

 said to closely resemble H. spinus. Hippolyte fascigera and 

 H. j)usiola have been both recorded, but I am unable to give any 

 details with certainty. 



In a genus like Hippolyte we find a large number of described 

 species, some of which are clearly distinct, others doubtful. I 

 have no practical acquaintance with the species under notice, 

 but it is worth remarking that whereas some of the species are 

 clearly southern in their distribution, others are as distinctly 

 northern, while others again are generally distributed. Now,
