out they become longer than broad and more or less oval, and the 

 small accessory plates diminish in number and cease, but the 

 large side accessories project. Towards and at the tip the acces- 

 sories are not seen, as they gradually diminish in size, and the 

 side arm-plates separate the upper arm-plates, which become very 

 small. 



The tentacles within the mouth are large and stumpy, and those 

 of the arm are longer than the large tentacle-scale. The colour 

 of the whole is light brownish red, and there is a blotch of dark 

 colour on the radial shields and sometimes on the centre of the 

 disk. The arms are dark red-brown close to the disk for a short 

 space, and then they are slightly ringed with alternate dark red 

 and light buff. In some instances the spines in the interbrachial 

 spaces are dark-coloured. 



There is much variation in the colouring and marking ; and as 

 the animal dries, the colours become lighter, the red disappears 

 and is succeeded by a buff tint.

 The disk is flat above, circular in outline, and small ; and the 

 arms are moderately slender and tapering, and about four or five 

 times the diameter of the disk in length. The colour of the 

 upper part of the disk and arms is purple and light buff. The 

 light tint is in four blotches on the disk, one in each interradial 

 space, and the radial shields have a light mark on them, as have 

 also all the scales and notably the few larger ones. The arms 

 look banded with the light and dark tint ; and two or three npper 

 arm-plates are darker than the succeeding one, and have, besides, 

 a longitudinal light area and a little spot near the end, besides 

 lateral purple stripes and tinting. The accessory plates are 

 generally tinted light purple, and some of the spines are banded. 

 Beneath, the colour is light buff; and there is no colour orna- 

 mentation until quite at the tip. 



The disk-scales are small, numerous, and without order ; and 

 the radial shields are very small, swollen, long-oval in shape, and 

 very distant. Beneath, the scaling is distinct and small, and there 

 is no other colour than the common light tint ; it reaches close to
