1070 SIR CHARLES ELIOT OJT 



sliapect ^^ on a raised base, 18 in number, generally simple but 

 some are forked ; one quite arborescent, bipinnate. Pinnules 

 rudimentary. The gills are completely retractile and gill -pocket 

 can close over them. Rhinophores fully extended ; numerous 

 fine white lines on deep crimson ground, otherwise perfoliations 

 hard to see ; completely retractile. Head distinct, with pro- 

 minent tentacles. 



" General colour greyish white, but this is plentifully sprinkled 

 with clear white opaque marks, so that general appearance is 

 white. Ov^er the borly this is covered with a delicate network of 

 crimson, the mantle being sprinkled with clear spots of the same 

 colour. Edge of mantle bordered with a thin clear line of bright 

 orange-yellow. A broad crimson line runs up each angle of each 

 gill rhachis." 



Mr. Crossland adds in a letter : " The margin is much more 

 ample than in other species known to me. I have never seen one 

 before in which the undulations are so deep or keep in such 

 constant motion." 



Riippell and Leuckart's diagnosis is " Colore lacteo, pallii 

 margine sulfureo-limba.to : dorso venis punctisque sanguineis 

 notato : bra.nchiis 19 circiter, pinnatis." They also say that the 

 branchife are " pyramiden-formig," which corresponds to Mr. 

 Crossland's observation that the pinnules are rudimentaiy. The 

 coloration is sufficiently distinct to make the identity of this 

 animal with Riippell and Leuckart's Do7'is tinctoria certain. 



The preserved specimen is somewhat distorted but the breadth 

 of the ma.utle margin is still noticeable, and the shape is not that 

 of an ordinary Chromodor'is. The internal characters appear to 

 be those usual in the genus. Though the outer surface of the 

 liver is purple wherever it is covered by the hermaphrodite gland, 

 3'et the organ itself is of a deep black and leaves a strong stain. 



The labial armature consists of two dark piu-ple plates. 



The rhachis bears thickenings much as in (Jhr. reticulata, and 

 the radula is of a type common in the genus. The inner laterals 

 are low and flattened, the innermost bear 3-4 denticles on either 

 side ; the rest are denticulate on the outer side only and the 

 number of denticles rises gradually from 5 (on the second and 

 third laterals) to 15 or more. The teeth at the same time become 

 tall and elegant in shape. There are about 60 laterals in all. 

 The marginals are denticulate on tlie tip only but are not 

 degraded to mere plates.
