opens perpendicularly, with prominent lips or jaws, that on the left 
side being of a fine blue colour, and the other red. At a short 
distance behind this, on each side, is a folded and slightly thickened 
membrane (4); and still further back, above, there is a more slender 
process on each side (the tentacles) (¢) ; while rather below the first 
named, on the right side only, is a smaller red process, encompassed 
at its root with a bluish circle (reproductive orifice?) (d). The eye 
is small, scarcely to be discerned, and is situated near the root of 
the more posterior process of the two already named. The body, on 
which these processes are placed is of a decided yellow colour, and 
ends in an oval mantle of rather small dimensions, with a border 
that constitutes the gills; while the more extended lateral portion, 
which is of a lively yellow colour, is separated from the dorsal by a 
line or groove, which seems to form the line of distinction between 
it and the sexual organs. A border or separated fold of this lateral 
division, of a bright red colour, proceeds forward from the hind- 
most border of the mantle, where there appears to be an opening 
into the body, to end on the side, at about half its length. The 
foot (e) is of dark brown colour, a little the widest in front, and 
slightly projecting behind, where the lateral portion of the body 
also slopes down, a small portion of the latter having above it a 
curved line of separation. The whole of the body, with the excep- 
tion of the mantle and foot, is marked with tints of red on the 
brilliant yellow surface. 
Of the other example above referred to, the colours had all been 
resolved into a dull brown, and the foot was much puckered. I 
could not discover in the lips or jaws any roughness or firmness as 
of teeth ; and the single lateral process at the side of the neck was 
absent. The internal plate (fig. 2) is in figure half an oval, 2 
inches wide, thin, subcartilaginous, and marked with faint lines di- 
verging from the straight border. Almost, but not exactly, at the 
middle of its upper portion was a slight prominence or projection, 
but so injured as not to be accurately defined. Its surface was very 
slightly tinged with brown.

Since my former communication * to the Zoological Society upon 
this subject, the same collector, Enrique Arcé, who furnished the 
materials for my paper, has been working industriously at the Or- 
nithology of Veragua, and has accumulated so much material in 
my hands that I now deem it expedient to draw up a report on the 
additions made to my former list. Besides mentioning the species 
added to the catalogue of the birds of Veragua, I have again inserted
