Also gained admission into my "Monograph" on the strength 

 of a single female carapace, dredged probably off Holy Island. 

 The shell now under notice belongs to the male, and was dredged

 am indebted to my friend Mr. D. Kobertson, of Glasgow, who 

 has more recently taken it abundantly in Kilchattan Bay, Ayr- 

 shire.
