 Mr. Bate from a mutilated specimen, the colour of which, 

 when dead, was greenish. It is named in compliment to 

 Mr. Barlee, a gentleman who has been most successful in 

 his exploration of the seas that wash the Shetland islands, 

 where he has discovered many Mollusca and Zoophytes to 

 be abundant, which are either rare or not found in more 

 southern parts of the British seas. 



Hippolyte Prideauxiana, Leach. — A very small species 

 with a straight beak, unarmed above, and with one or two 

 spines beneath in front.
