Common almost everywhere as far up as the 

 Gareloch, in 5-40 fathoms, usually on hard ground. 

 The majority of the females taken in March were 

 with ova, and we also found some in a similar con- 

 dition in July. The toothing of the rostrum is. 

 remarkably constant, the formula deduced from a 

 large number of specimens being l:§, the teeth on 

 the lower border always very minute. A small 

 Bopyrus is occasionally found in the branchial 

 chamber.
