The Type of Cypraea caput-anguis Philippi. — With a view of ascertaining 

 whether the type of this species was really lost, I wrote to Dr. Philippi himself. 

 His son kindly answered my enquiry as follows : — ■ 



"Santiago, 15 Juin, 1902. 

 Monsieur ! 



Le typ de Cypraa caput-angiiis se trouve ici au Musee, faisant part 

 de la collection de coquilles que mon pere a vendu au Gouvernement de 

 Chili ii fait long temps, la meme qu'il avait apportee d'Allemagne. 



Votre tres devoue,

Helix nemoralis m. sinistrorsum in Switzerland. — Whilst staying a few 

 days at Corbeyrier sur Aigle, in July last, I found within one hundred yards of the 

 Hotel Victoria a very fine specimen of the above, fully grown, and of the typical 

 iive-banded form. I also took most of the species that I found there in 1896, but 

 in addition I got Helix lapicida and a fine series of //. kortensis vars. incaniala 

 and lilacifta. — Edward Collier {Read before the Society, Oct. 14, 1903).
