1922 Excerpt: ... (Plate 9, Figures 10 to 12.) Echinolampas
antillarum Cotteau, 1875, Kongl. Sven. Vet. Akad. Handl., vol 13,
No. 6, p. 19, plate 3, figs. 9 to 12. Echinolampas ommserpentis
Guppy (pars), 1882, Scientific Assoc. Trinidad, Proc., part 12, p.
196. The following is an extract from the original description of
this species: Species of medium size, oval, elongate, rounded
anteriorly, subtruncate posteriorly; upper surface very little
swollen, lower face cushion-shaped; 1 Quart. Jour. Geol. Soc.
London, vol. 67, p. 685. rounded on the border, concave in the
middle. Apical disk subcentral anterior to the center. Ambulacral
areas are narrow, elongate, nearly straight, flush, narrowing at
the tips, which, however, are widely open. The posterior ambulacra
I and V are a little longer than the others; poriferous areas are
narrow, not depressed, with unequal pores; the internal rounded,
the external elongate, narrow, and oblique. The poriferous areas
only cease to be petaloid at a very short distance from the border.
Tubercles are scrobiculate, scattered, abundant, a little less
crowded on the upper face than in the marginal region. Peristome
opening in a depression of the lower face. Periproct transversely
elongate, angular, placed very near the border. There is only a
single specimen in the Washington collection. It measures 15.5 mm.
in height, 33 mm. in length, and 29 mm. in width. Of this species
Cotteau says it is very rare, but he does not say how many
specimens he had, other than mentioning both the Cleve collection
and the Museum at Upsala. The Cleve specimen differs so much in
measurement from Cotteau's figures, and moreover is so imperfectly
preserved, both dorsally and ventrally, that it is quite probable
that Cotteau figured and made use of the Upsala specimen...
