obliquely, and retractile into tubular cavities. Foot nearly as 

 wide as the mantle, much elongated, rounded in front, tapering 

 posteriorly to an acutely rounded tip, which projects some dis- 

 tance behind the mantle. 



Color subpellucid, colorless, with a median longitudinal cream 

 yellow stripe, extending from the inter-tentacular space to the 

 branchial star ; on each side of the dorsal stripe is a bright buff 

 colored one, which does not extend anteriorly quite as far, and 

 passes around the branchial star posteriorly ; the stripes are 

 separated by a dark purple line, and the lateral stripes are 

 margined by a narrower and paler line of same color. Mantle 

 margined with cream yellow, with the addition on the front end 

 of an intra-marginal violaceous band. Upper fourths of the 

 branchial plumes violaceous. Tentacles on their basal third 

 orange red, the middle third purple, and the upper violaceous. 

 The under surface of the animal colorless except the mantle, 

 which is margined with cream yellow. 



Foot tipped with violet on its upper posterior end. 



Length, one and a half inch. 

 Habitat, Tahiti. 



Chromodoris maculosa, Pease. Plate 7, fig. 2. 



Animal subcylindrical, elongate, narrow, smooth, flaccid, sub- 

 pellucid. Mantle dilated in front and rounded, rounded behind, 

 sides nearly parallel. Cervical tentacles large, sub erect on stout 

 bases, elongate oval, laminre deeply incised, retractile into sim- 

 ple cavities. Branchial star moderately developed, consisting of 

 eight sub-erect, lanceolate, narrow pinnate plumules, connate at 

 their bases, and retractile into a common simple cavity. Vent, 

 a simple orifice. Labial tentacles small, finger-shaped. Foot 

 elongate, narrow, truncately rounded and fissured in front ; 

 acutely rounded and projecting far beyond the body poste- 

 riorly. 



Color cream yellow, margined with fulvous, on which there is 

 a series of abbreviate reddish lines, three irregular radiating, 

 fulvous lines, extending from the front margin of the mantle 

 toward the tentacles ; lineated longitudinally with opaque white, 

 lines four, the two median encircle the branchiae and pass between 

 the dorsal tentacles, which they partly encircle, the two lateral 

 lines extend from the tentacles to the posterior end of the body ; 

 the spaces between the lines dotted with purple. Cervical ten- 

 tacles pale, a broad brownish red zone on their basal half, and 

 one narrower red zone just below the apex. Branchial plumules 

 pale slate color tipped with red. Upper surface of the foot and
