The colours of the tentacles have not been separately tabulated. Usually the 
ends (distal branches) are darker than the stalks and show the general colour of 
the body. The stalks are sometimes whitish, or colourless, or again, more or less 
of the darker tints of the ends run down upon them. 
2. Distribution of Colour on the Body. 
In Table VIII. it is shown that 12 % of the adult and only 4 "/^ of the young 
are uniformly coloured. In all such cases browns and generally dark tints like 
seal and clove prevail. The mid-dorsal region is uniform in 60°/^ of the adult, 
and in only 13 "/^ of the young. Here again are the browns exclusively. When 
the colours of this region are mixed the dark browns like seal, clove and Vandyke 
are predominant, with some intermixture of creams and grays, in both the ground- 
colour and the markings, of the adults. In the young, while the browns of lighter 
tints prevail in the ground-colour, the creams and especially the grays and white 
are in excess in the markings. 
The lateral-dorsal regions present much more variegation, since only 28 of 
the adult and 6 7o of the young are uniform and there is a decided turning to the 
lighter browns and creams. Wheu the colours are mixed the browns still pre- 
dominate in the adult, although the markings are somewhat lighter, while in the 
young the ground-colour and markings are proportioned about as in the mid- 
dorsal with some increase of the creams. 
The ventral region in the adult shows a return to greater uniformity (57'5 °/^) 
but now the tints are among the lighter browns and the creams, while only 33 % 
of the young are uniform, with the browns, creams and grays about evenly re- 
presented. When the colours are mixed there is in the adult a decided increase 
of the creams in the ground-colour with more of the browns in the markings, 
while for the young in the ground-colour the creams, and especially the grays, 
increase, and in the markings the browns are equalled by white, each being 
only one-seventh, while the creams and grays make together five-sevenths, of 
the colouration. 
In the adult the percentage of creams is doubled from mid- to lateral-dorsal 
and again from lateral-dorsal to ventral, thus gradually changing the colour from 
the dark brown back to the lighter belly, but even here the browns are pre- 
dominant. In the young the increase in creams ventral is not so marked but, 
added to the very large percentage of grays over the whole body, gives the light 
and variegated colouration which so generally strikingly characterizes the young 
of H. floridana and may lead one upon superficial examination to class such indi- 
viduals with H. grisea Selenka. Pourtales, 18.51, p. 13, noted that the young "are 
of a lighter colour than the old individuals." Herouard, 1902, p. 8, describes 
the colour, at the moment of capture, of one specimen as greenish, dotted with 
brown spots upon the back, while the ventral surface is uniform, and he describes 
another as having, in addition to the brown dots, spots more extended and of 
a lighter brown. Clark, 1901, p. 258, notes great variation in colour. 
In general in both adult and young, as graphically represented in Plates I. and
