The specific title originated with Daudin, who applied it to the original of plate 
ix. in Russell’s second volume. A specimen now in the British Museum collected by 
Russell and labelled from the Sunderbunds is, without doubt, this very specimen; for 
Russell, on the last page of this volume, mentions the Sunderbunds as the locality 
from which the original of this plate was obtained. Mr. Boulenger omits to record 
the discovery of this type, which had previously been lost sight of. 
With this species, I am of opinion, should be united several forms previously des- 
cribed as distinct by various authors, and considered as such by Mr. Boulenger in his 
Catalogue (1896). All of these appear to me to be separated on insufficient grounds 
affecting shields, which analogy shows to be inconstant in many individuals of certain
