1906.] OF SOUTHERN INDIA AND CEYLON. 643 



The coloration is not uncommon, and it is quite possible that 

 the species has been described again with a fresh name, but I 

 cannot identify it with any other form. 



Ohromodoris tennentana (Kelaart). (Plate XLIII. fig. 1.) 



(Kelaart, 1. c. III. p. 268.) 



This appears to be another Ohromodoris with an ample mantle- 

 margin. In colour it offers analogies to Chr. ohsoleta (Riippell & 

 Leuck.), Chr. impericdis (Pse.), and Chr. atireopurinvrata Colling- 

 wood, but does not agree completely with any of them. 



Chromodoris diardii (Kelaart). (Plate XLIII. fig. 2.) 



(Kelaart, 1. c. III. p. 267. 



= Chr. semjyeri Bergh in Semper's Reisen, Heft xi. pp. 482- 

 484.) 



The resemblance in coloration seems to me sufficientl}'- strong 

 to justify the identification of these two forms. Chr. rimcinaia is 

 nearly allied, but neither Kelaart's description nor his figure gives 

 a hint of the conspicuous spherical glands beneath the mantle- 

 edge. 



I regret to substitute Kelaart's name for that given by Bergh, 

 bu.t follow the precedent of the latter authority, who has changed 

 his Chromodoris elizahethina into Chr. quaclricolor (Riippell &, 

 Leuckart). See Bergh in Samper's Reisen, Theil vi. Lieferung ii. 

 p. 68. 



Chromodoris gleniei (Kelaart). (Plate XLIV. fig. 1.) 



(Kelaart, 1. c. I. pp. 294-5.) 



This form appears to be clearly a Chromodoris in virtue of its 

 general shape and simply pinnate branchiae. It is said to be 

 found " in the Inner Harbour (Tiincomalee), as also at Oottiar 

 opposite Fort Frederick," and will probably be identified without 

 difficulty on account of its striking coloi-ation. Kelaart's picture 

 has probably faded, for he describes the back as bearing " a deep 

 golden- coloured patch, bordered and spotted with purplish red," 

 whereas in the plate the patch is reddish brown with a margin of 

 spots of the same colour but darker. The mantle appears to be 

 ample ; and the animal probably belongs to the same group as 

 Chr. reticidata, Chr. syhesi, Chr. cavcB, &c., and may even be 

 identical with the last of them, in which case the name gleniei 

 has priority. Chr. alderi (Collingwood, Trans. Linn. Soc. ser. 2, 

 Zool. vol. ii. 1878, p. 132) also presents resemblances. 



Chromodoris inopinata Bergh. 



(Bergh, Siboga-Expeditie, Opisthobranchia, 1905, pp. 157-9.) 



This species is allied to Chr. sykesi Eliot (Proc. Zool. Soc. 1904, 

 i. pp. 387-8). It has the same shape and a similar though not
