CKASIA. 37 



these circumstances, I consider it to be my duty, to say, in 

 respect to the note referred to, that I am confident my old 

 friend never intentionally led us into error ; nor do Professor 

 Forbes and Mr. Hanley state otherwise. The fact is, that 

 Dr. Turton was a man of great simplicity, and so far from age 

 giving an increase of caution, it appears, with him, to have had 

 a contrary effect ; if it were necessary, I could relate several 

 curious and laughable stories of his being duped by the frauds 

 of crafty shell-dealers. Whilst I admit that Dr. Turton lent 

 too credulous an ear to the impositions of unscrupulous com- 

 municators, which has impaired our dependence on the habi- 

 tats of various doubtful testacea recorded in his ' Conchologi- 

 cal Dictionary/ I trust I have cleared the memory of my 

 friend, to whom British conchology is much indebted for his 

 care and nurture, from every suspicion of gross and indesinent 

 error : we must not forget that Dr. Turton and the excellent 

 Montagu fanned the flame of this branch of natural history 

 when almost extinct, and its supporters were few and far 

 between. 



CRANIAD.E. 



This family has one genus and one recent species.

C. anomala, Brit. Moll. ii. p. 366, pi. 56. f. 7, 8, and pi. U. f.2 (as 

 Norvegica). 



Animal with pale pink, fringed, spiral arms. The ovarium 

 is red-brown, and deposited partially on one of the lobes of the 

 mantle. It is taken plentifully in Scotland. It is to be hoped 

 that some qualified northern or wayfaring naturalist will fur- 

 nish science with a more extended account of it, and of the 

 Hypothyris caput serpentis, as I apprehend it will be long 

 before an additional recent species will occur.
