Seeing that this description appeared in the Proceedings of the
Zoological Society of London 1846, a sense of déjà-vu was
aroused after our recent experience collating the Pfeiffer
descriptions of
Helix strumosa
and
Tudora nobilis,
which were read to the Zoological Society of London on March 9, 1852
and appeared in the Proceedings ... 1852, saw actual
publication over two years later, some research seem prudent. The
issue was finally resolved after the discovery of on-line version of
ZSL (1893), which is a concordance of the early years of this
journal. The process of discovery was long and tedious due to the
byzantine organization of the digital library directories involved.
As it turns out the Pfeiffer description was published later in the
year of its reading. Pfeiffer, L., 1846. Descriptions of thirty new species of Helicea, belonging to the collection of H, Cuming, Esq. Proceedings of the Zoological Society of London 1846: 28-34. May. (On-line) ZSL (Zoological Society of London), 1893. List of the dates of delivery of the sheets of the "Proceedings' of the Zoological Society of London, from the commencement in 1830 to 1859 inclusive. Proceedings of the Zoological Society of London for the year 1893: 436-440. (On-line - Page 438) |
