In his interesting study of these engraved shells, in Lindiaka ii., Professor Blinkenberg has compiled a list of these objects so far published or mentioned. In regard to the first section of that list, which deals with Asia, the failure to observe the late Professor L. W. King's observations on this subject have led to some errors in the list which may cause loss of time and labour to future students. The following notes, based upon the numbers in Blinkenberg's list, are intended to be of use in avoiding further confusion.

Nos. 1 and 2, Layard, Discoveries in the Ruins of Nineveh and Babylon, p. 563, below and above, are respectively the inside and outside of the same fragment, although Layard speaks of ‘fragments.’ Registration no. 51–1–1, 176; no. 117997. Layard's woodcuts are unsatisfactory, since the right-hand side of the lower one attributes to the design on the inside part of the outside design which completes the upper edge of the top woodcut. Found by Sir W. K. Loftus at Warka (Erech).
