The type, Plate 22, differs from specimens of 7’. nigra, equal in size, in 
being less convex on the back, the arch from the first to the fifth vertebral 
scale being lower, as also that across the back; the marginals above the legs 
are entire, not worn and thickened, and form greater arches, the eighth marginal 
is wider on its upper edge; the bones of the sternum above the gulars and the 
anals are not swollen downward; the anal notch is a little more than 90°; and 
the fifth vertebral scale is narrow on its upper edge and bears in its upper half 
a steep and sharp prominence. On similar comparison with 7’. microphyes it 
is seen that nearly all of these differences are pertinent. 
Specimen described is from the Boston Society of Natural History. Dr. 
C. F. Winslow collection (See Proc. Boston Society Natural History, 1861, 10

The type described and figured by Quoy and Gaimard was said to be twelve 
inches long and eight inches wide. It was obtained by Freycinet at the Sand- 
wich Islands (Hawaiian) from the Captain of a vessel that had recently (about 
1818) arrived from California. There is no mention of the original habitat.
