The following Dorids, described and figured by Kelaart, cannot be referred with certainty to any of the modern genera, but if rediscovered will perhaps be recognisable :- Doris elizabethina (Kelaart, I.e. II. p. 267) (PI. XLIII. fig. 3) has the appearance of a Chromodoris in most respects, but the fairly wide bipinnate branchiae would be abnormal in the genus. Doris papillosa (Kelaart, 1. c. I. p. 297) (PI. XLV. fig. 3) is coriaceous and bears large papillae. The back is covered with reddish spots and markings, but the rhinophores are green or blue. The three anterior branchiae are white, the three posterior reddish. In the plate the anterior plumes are hardly visible. Doris corrugata (Kelaart, 1. c. I. p. 303). The very poor drawing, which is not worth reproduction, represents a flat greenish-grey tuberculate dorid, with no spots. The erect, simply pinnate branchiae are conspicuous. It may be either a Sphcero-doris or a Staurodoris, and it will perhaps be possible to identify it by the greenish coloration of the upper surface and the black spots on the lower. Doris lockyerana (Kelaart, 1. c. II. p. 268) (PI. XLVT. fig. 1). This " splendid species" looks as if it might be an Asteronotus, but has evidently no resemblance to the D. exanthemata which Kelaart disliked so much. It may be an Orodoris. Doris viperina. ] These large handsome species are probably Doris picta, > Platydorids or Discodorids. The drawings of Doris bellicosa. J the under sides are not reproduced. D. viperina (Kel. 1. c. I. p. 299) (PL XLVI. fig. 2) is " coriaceous . . . . covered with short spinous tubercles." The drawing of the under side represents the oral tentacles as very large. Both the foot and the under side of the mantle are white and spotted with reddish brown. D. picta (Kel. 1. c. I. p. 303) (PI. XLIY. fig. 4) is said to be " coriaceous . . . . granular . . . . sheaths of rhinophores large, granular." The drawing of the under side represents the oral tentacles as moderately large ; the foot as wdiite ; the mantle-edge as white with a broad red border round the foot. D. bellicosa (Kel. 1. c. I. p. 303) (PI. XLIY. fig. 3) is " coriaceous . . . . granular, and covered with small spines." The figure of the under surface represents the oral tentacles as white and moderately large; the foot of a deep brick-red ; the mantle white, but largely covered with brick-red spots and blotches, especially near the foot. Doris variabilis (Kelaart, 1. c. I. p. 300). The drawing is very |
