68 BRAZIER : NOTES ON AUSTRALASIAN MOLLUSCA. 



derniestdides which }'0U have sent you may place in your 

 collection as Ainycla lineoJata Pease. Der/iiestdides- 

 is a variety oi Nassa cornicula Medit., and not your shell, 

 though near it. It is intermediate between the Genera 

 Nassa and Columbella, the inner lip being smooth and 

 columella truncate at base. Pray send me all the speci- 

 mens you can spare, e.specially varieties." In another 

 letter, the last he wrote, dated January 27th, 1871, "I wrote 

 you before that I have described the species which Angas 

 called CoIuinbeUa dermestdides to C. ]{neolata. I have 

 discovered since that the Mediterranean shell belongs to 

 genus ' Amycla' while your species is a true Columbella, 

 . the columella being dentate or laminate. I have been 

 obliged to change the name to Col. maculata." Having 

 found that Mr. Pease's last name was preoccupied, I wrote 

 to him on the subject, l)ut alas, he had gone over to the 

 silent majority. I had distributed a large number of 

 specimens under Mr. Pease's first name and consider, it 

 l)est to retain it. Mr. Pease described it in the American 

 Journal of Conclwlogy, Vol. VII. Part I. p. 22, , August,,. ,. 

 187 1, as CohanbeUa maculosa, so that his name of lineolala 

 had been in use twelve months before Mr. Tryon in Manual 

 of Condi ology Vol. V. p. 13^, says, "This species was 

 described by Mr. W. H. Pease as C. maculosa, a name pre- 

 occupied by Sowerby, having been previously confused by 

 Mr. Angas with C. dermesloldes Kiener, and by Mr. Brazier 

 with C lineata Pease — which, apparently by a slip of the 

 pen, he writes Imeolata. Pease's description of lineata (I 

 have no specimen, and it has not been figured) scarcely 

 covers this form, and I therefore give the species the name 

 under which it is so well known to Australian collectors." 

 It will be seen by Mr. Pease's letters there is no slip of the 

 pen on my part, but to give honour to whom honour is 

 due as I had every respect for the late William Harper 

 Pease as a jolly good fellow.
