224 BULLETIN OF THE 
Famity LIMIDA. 
Genus LIMA Brucrire. 
Lima squamosa Lamarck. 
Lima squamosa Lam., An. s. Vert., VI. p. 156. Sowerby, Thes. Conchyl., I. p. 84, 
pl. xxi. figs. 1, 18. 
Young specimens, in the condition called L. caribbea by D’Orbigny, were 
dredged in 80 fms. off Havana; in 100 fms. at Barbados; at Station 210, near 
Martinique, in 191 fms. ; and in 640 fms., Yucatan Strait ; all single valves ; 
one living specimen at Station 292, in 56 fms., sand, off Barbados, bottom 
temperature 74°.5 F. It has been found in Florida by Hemphill, and is 
widely dispersed over the world. 
Lima tenera Sowersy. 
Lima tenera Sby., Thes. Conchyl., I. p. 84, pl. xxi. figs. 2, 3, 10, 11, 12, 1846. 
Obtained by Sigsbee in 80 and 127 fms. off Havana; at Station 21, in 287 
fms. ; and at Barbados in 100 fms.; all the specimens being separate valves. 
A variety which may take the name of planulata was obtained at the last- 
mentioned station. It is distinguished from the ordinary varieties by being 
more elongated and compressed, by finer and smoother sculpture, which wants 
the little spurs or spines on the radiating ribs, which are flattened and sepa- 
rated by narrow deeply punctate channels. In full-grown specimens the 
inner basal margin is smooth and thickened all round, while the margin of 
the gape is pouting and more marked than in the type. This variety is flatter 
than any form of Zima which has been figured, and at first was naturally sup- 
posed to be a distinct species. There seem, however, to be intermediate speci- 
mens, and I think it is quite certainly an extreme form of L. tenera. 
Lima inflata Lamarck. 
Lima inflata Lam., An. s. Vert., VI. p. 156. 
Lima fasciata Sowerby, Thes. Conchyl., I. p. 85, pl. xxi. figs. 16, 17; not Ostrea 
Jasciata Linné. 
Valves of this species were dredged on the west coast of Florida in 19 fms., 
and off Sand Key in 128 fms. Fine specimens have been obtained by Hemp- 
hill at Cedar Keys and Key West on the reefs, and it extends along the 
Atlantic coast northward nearly or quite to Cape Hatteras.
