Other species of Melo (M. georginae, for example) probably should 
be added to the list. 
The largest and, really, the only large Chiton is Cryptochiton stel- 
leri, reaching 18.50" in length. 
In the same size class, but not as well known, is a large "Worm 
Shell," Siliquaria pone Soe at 18.39". Other “Worm Shells" of 
aberrant genera such as Kuphus probably exceed this length, although 
not listed. 
The remaining mollusks which exceed a foot in length are not very 
numerous. They include a few members of the families Cassidae, 
Strombidae, Turbinellidae, Ostreidae, Muricidae, Spondylidae, and 
Bursidae, in that order. A list follows:

This completes the list of species recorded at a foot or more in 
length. An additional 65 species, including 15 additional families, 
reach lengths of between 8 and 12 inches, but a list of these would 
unduly lengthen these notes. 
"World Sige Records” are apt to be ephemeral, with new records being 
Continuously added. Gavesthoieesy it is unlikely that the overall 
Picture is going to be substantially changed, and it is apparent 
that really large shells make up 4 very small minority of known 
species. The approximately 100 species exceeding 8 inches in maxi- 
mum length constitute no more than two tenths of one percent of even
