A. E. Verrili—Marine Fauna of North America. 313 
Acanthodoris ornata Verrill, sp. nov. 
Length about 1 inch, or 25™™; breadth 8™™, Body elongated, 
high at the sides, somewhat oblong: but narrower and obtusely 
rounded behind, extending much beyond the mantle; mautle 
much smaller than foot, broadly rounded in front, and expanded 
into rounded antero-lateral angles, narrowed and often incurved 
in middle and again expanded opposite the gills, covered with 
small, conical papille, except on a smooth area on the middle 
of the back, extending from the gills to the tentacles. Frontal 
veil broad, angular, with four distinct, but small, papilliform 
processes, two directed forward and two at the prominent outer 
angles. Dorsal tentacles long, slender, tapered at the end, length, 
nearly equal to breadth of body (6™™), the lower half smooth, 
the distal half with about sixteen strong lamella, and a terminal 
rounded papilla; sheaths radimentary, with very small papille. 
Gills eight, large, broad, in expansion exceeding the breadth of 
the body, bipinnate, finely divided, the two posterior ones 
smaller, all united by a basal web; anal area smooth. Color, 
translucent yellowish flesh-color, specked with yellow and 
rown ; bases of papillz surrounded by brown; dorsal smooth 
area brownish (due to viscera); gills pale flesh-color, with flake- 
white at their bases; tentacles pale, their lamelle brownish 
yellow. (Description from living specimen).

Doris bifida Verrill, this Journal, vol. 1, p. 406. (Variety). 
Typical specimens of this species have been repeatedly col- 
lected and carefully examined by me, from various parts of the 
New England coast (New Haven to Eastport, Me.), and agree 
ia with the figures and descriptions by Alder and 
ancock, except that the white stellate markings on the gills 
are usually absent. My Doris bifida is only a color-variety. 
Acunthodoris citrina sp. nov.

Pansion nearly reaching the sides of body, the two posterior
