72 THE NAUTILUS. 



vial two shells which I took alive from among the feathers of freshly- 

 shot Bob-o-links here at San Carlos Estate, Guantanamo, Cuba. I 

 shall be very glad to know what this Bob-o-link shell is. Is it a 

 Cuban shell, or did the birds bring this shell from some more south- 

 ern country, and if so, from what country? [The shells are Suc- 

 cinea riisei, a species known from St. Croix and Porto Rico.] This 

 will throw some light on where the birds spent the last few days 

 before starting for Cuba, as the shells were alive and the birds were 

 shot on the second day of their arrival. This is doubly interesting 

 to me, as I am interested in both conchology and ornithology. 

 This may also prove how certain shells are distributed. Did you 

 ever know of shells being found alive on birds? Not in them but 

 on them. If not, it seems to me that a note for the NAUTILUS is in 

 order. CHAS. T. RAMSDEN. 



FERGUSONI. A regrettable omission occurs in my dis- 

 cussion of a Long Island Acmsea (A.fergusoni Wheat) in Science 

 Bulletin, Vol. 2, No. 2, pp. 17-20, published July 16, 1913, by the 

 Museum of the Brooklyn Institute of Arts and Sciences. I have 

 just discovered in " The Molluscan Fauna of New Haven," by 

 George H. Perkins, Proc. Boston Society of Natural History, vol. 

 xiii, pp. 109163, on p. 127, the description of a single specimen of 

 Tectura testudinalis from the vicinity of New Haven, "the only 

 specimen that I have seen from here." Mr. Perkins' description is 

 excellent, and proves the identity of his specimen with A. fergusoni 

 from Hempstead Bay and "Wading River, L. I SILAS C. WHEAT. 



CHOANOPOMA (RAMSDENIA) MIKIFICA Preston, Proc. Malac. 

 Soc., London, x, p. 323, June, 1913, was sent me by Mr. Chas. T. 

 Ramsden with the request to compare it with Ctenopoma nobilitoium 

 Gundl. I find that it agrees perfectly with Gundlach's species, of 

 which part of the original lot is before me. H. A. PILSBRY. 



MR. J. H. FERRISS is on his way, by team, to the White Moun- 

 tains of Arizona, which have never been explored by a conchologist. 

 It is rumored that the Sonorellas are in a panic.
