MARINE FAUNA OF ST. ANDREWS. 
mela, Lithodes , Gebia deltura , Hippolyte spinus , and Dory- 
pliorus Gordoni. 
In contrast with the fauna of St. Andrews, we have in the 
mild sea of the west of Scotland the fine velvet crabs {Portu- 
nus puber) amongst the seaweeds between tide-marks. The 
common lobster is also much more abundant, though the 
wholesale fishing has of late years told severely on this crusta¬ 
cean, even on the most remote shores of the Outer Hebrides— 
as, for instance, off the rocks of Haskeir near the north-west 
point of North Uist, where thefrequent inroads of the fishermen 
with their lobster-pots and floats have rendered even the seals 
less frequent in their accustomed haunts. Xantho , Munida , and 
the rarer species of Crangon and Hippolyte are also absent from 
St. Andrews. In the south of Britain, again, are the splendid 
spiny lobsters off the rocky shores, velvet crabs, Pirimela , and 
Ebalia under stones between tide-marks, Alpheus ruber and 
Pagurus cuanensis in littoral pools, Pilumnus in the crevices 
of the tidal rocks, Pagurus Prideauxii with the beautiful 
Adamsia adherent to its protecting shell, Maia *, Dromia , and 
Polybius. In the northern waters swarms of the hardy Por- 
tunus pusilluSj P. tuberculatus , Pagurus pubescens , and Pandalus 
hrevirostris are characteristic, besides the rarer Pagurus tri- 
carinatus , Crangon serratus , and Sabincea septerncarinata . 
I am indebted to the Rev. A. M. Norman for kind assist¬ 
ance with several species of Pakemonidee and Galatheidaj. 
Suborder STOMAPODA. 
Fam. Mysidse. 
Genus Mysis, Latreille. 
Mysis jlexuosa , 0. F. Muller ; Bell, Brit. Crust, p. 336 
(as M. chamceleon ). 
Very abundant in rock-pools. 
* It was recently stated in ‘ Land and Water ’ that Maia squinado had 
been procured near the Bell Rock; but, by the kindness of Mr. F. Buck- 
land, who forwarded the specimen, I am enabled to observe that it was 
only Lithodes maia.
