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 Afriea ; 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. Rhinophores 
clavate, the apex pointed and bent rather backwards, laminated low 
down, their cavities with raised crenulate border. Branchie 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, trun- 
cate 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 INFRANZVATA, 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 strize, retractile within cavities, with the mar- 
gin raised, denticulate and contractile. Branchize 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 aud behind; transversely grooved, 
with the upper lamina notched, in front. 
Colour (in spirit) light brownish ; above, sparingly clouded with epi- 
dermic 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.
