Doris GRANULOSA, sp. noy. (Plate XXIX. figs. 1-3.) 
Body oblong-elliptic, not very depressed. Mantle ample, pre- 
senting a granular appearance from a close covering of small, sessile, 
unequal, rounded tubercles. Rhinophores minutely laminated, rather 
slender, subconical or pyriform (in one specimen the apices are 
slightly enlarged and rounded) ; their cavities are wide, and have the 
margins produced into short tuberculated and denticulated sheaths, 
Branchiz 8,rather short, slender and spreading, bipinnate, surrounding 
the short tubular anus in a circle interrupted behind ; the two hinder- 
most plumes are deeply divided; the margin of their common cavity 
is nearly smooth. Oral tentacles small, free, flat, and linear. Foot 
oblong, truncated and transversely grooved in front, with the upper 
lamina deeply notched, the lower slightly so; the posterior extremity 
is rounded, and the border flattened. 
Length (in spirit) 17 millims., breadth 11. 
The colour of the preserved specimens is a dirty yellowish.

Doris LoNGULA, sp. nov. (Plate XXIX. figs. 4, 5.) 
Body oblong, rounded at both ends. Mantle ample, covered with

produced. Branchize 12, small, slender, bipinnate, in a complete 
circle round the tubular anus; retractile in a wide cavity with 
minutely and irregularly denticulated margin. Oral tentacles small 
and linear. Foot oblong, rounded at the ends, transversely grooved 
in front, with both laminze notched ; it reaches behind to the edge 
of the mantle ; and its border is free and flattened.

Doris cucunuata, sp. nov. (Plate XXIX. figs. 11, 12.) 
Body oblong, raised. Mantle widely expanded, somewhat like a 
hood, over the head ; elsewhere with the border but little developed,
