STREPTOSTYLA. 
Spirazis, sect. 1. Glandineformes s. Streptostyla, Shuttleworth, in Bern Mittheil. 1852, p. 203. 
“‘Shell oblong, attenuated below; aperture narrow; outer margin often inflexed ; 
columella strongly contorted, furnished with a callous lamina, deeply intrant, and 
scarcely truncate anteriorly ” (H. &@ A. Adams). The living animal elongated in its fore 
part, with small triangular labial palpi in addition to the four feelers; eyes as in 
Glandina. ‘Teeth of the radula narrow, spiniform; median tooth present. Mode of 
life similar to that of Glandina. 
The majority of the species have a quite smooth shining shell; therefore this 
character will not be repeated for each species in the following table, but only the 
exceptions mentioned. 
Living animal—see Fischer & Crosse, Miss. Scient. Mex., Mollusca, i. t. 2. fig. 15 a, and 
Strebel, Beitr. Mex. Land- und Siissw.-Conch. iii. t. 22. figg. 2, 3; an exact account of 
the anatomy is to be found in the same works. 
Like Glandina, this genus is pre-eminently Central-American, and its distribution 
within our limits is very similar; a few rather aberrant species are also found in the 
West Indian islands—S. cubaniana, S. moreletiana, S. suturalis, S. episcopalis, all in 
Cuba. But the northern limit of this genus lies in Mexico itself, and also towards the
