This genus was first characterized by the Rev. 

 Dr. Norman, but his name — Doryphorus — being pre- 

 occupied in zoology, that of Caridion was sub- 

 stituted by Goes.

Lamlash Bay, two specimens, 1853 (Norman). Not 

 uncommon throughout the Firth, especially in deep 

 water ; our largest specimen measures IJ inches in 

 length, and was taken near the head of Loch Goil, 

 in 5-10 fathoms. Females with ova in March. The 

 toothing of the rostrum is tolerably constant, the 

 formula being \^, 



Genus Pan D ALUS, Leach. 



PANDALUS ANNULICORNIS. 



Pandalus annulicornis. Leach, Malac. Brit. pi. xl.— M. Edw., 

 Hist. Nat. des Crust, ii., p. .384.— Bell, Brit. Crust, p. 297. 



Abundant and fine everywhere in 30-105 fathoms, 

 on a muddy bottom ; smaller specimens common in 

 shallow water in all parts of the Firth. Many 

 examples from deep water, especially those taken 

 in Loch Fyne, have the beautiful red tinge so 

 characteristic of deep-sea Crustacea. The toothing 

 of the rostrum varies considerably in different 

 individuals ; in a large number which we examined 

 for the purpose we found it t^i^i^i:^-. Several of our 

 largest specimens measure 4J inches in length. 

 Phryxus ahdoininalis occurs not infrequently on 

 the abdomen, and a Bopyrus is occasionally found 

 in the branchial chamber.
