Show 248 MR. P. S. ABRAHAM ON THE [Mar. 6, surface. Underneath, a close, black, minute freckling is usually found on and near the sides of the foot, but not elsewhere. In a large spirit specimen the length was 82 millimetres, the breadth 59, the height (or thickness from the middle of the back to the sole of the foot) 15. Hab. South Africa ; Seychelles ; Sir C Hardy's Islands. The mantle is highly spiculose, the spicula being numerous and close, crossing each other more or less at right angles, nearly straight and cylindrical in form, and with blunt ends. They are rather massed together in bundles. The odontophore is comparatively small, and bears about 26 transverse rows of numerous small, well-curved, lateral spines. DORIS INFRAMACULATA, sp. nov. (Plate XXVII. figs. 5-7.) Body depressed, oblong-elliptic Mantle leathery, finely granular above, with a wide, irregularly crenulate border. Rbinophores clavate, the apex pointed and bent rather backwards, laminated low down, their cavities with raised crenulate border. Branchiae 6, tri-pinnate, spreading: the anus short, with its margin digitate ; the general cavity has the edge raised, smooth, or sublobulate. Oral tentacles small, subconical, and grooved above. Foot oblong, truncate in front, rounded behind, with a small transverse anterior groove, having the upper lamina notched. Colour of the spirit specimens light-brown, with irregular patches of dark-brown situated between the minute granular tubercles of the upper surface, principally upon the mantle-border. Underneath, upon the sides and upon the mantle-expansion, are some large and small chocolate-brown spots. Length (in spirit) 50 millims., breadth 34. Hab. Amboina. The odontophore is proportionally larger than in D. coriacea: it bears about 30 transverse rows of lateral recurved spines. DORIS INFRAN^EVATA, sp. nov. (Plate XXVII. fig. 8.) Body oblong-elliptic, depressed. Mantle widely expanded all round, with a wavy and irregularly crenulate border, covered above with very minute granules. Rhinophores clavate, with the upper half diagonally laminate and conical, the lower rather swollen and marked with transverse striae, retractile within cavities, with the margin raised, denticulate and contractile. Branchiae 6, bipinnate ; the anus long and tubular ; the general cavity with the wall produced, 6-lobed, and completely contractile. Oral tentacles sublinear, flattened, or longitudinally indistinctly grooved on the upperside. Foot oblong, rounded before and behind; transversely grooved, with the upper lamina notched, in front. Colour (in spirit)light brownish ; above, sparingly clouded with epidermic intergranular brown ; beneath, with scattered, unequal, dark-brown freckles upon the mantle-expansion all round, near the foot. Length (of a large specimen in spirit) 42 millims., breadth 28. Hab. Mediterranean Sea. |
