Queries for Dr. Günther

(1) In my notes from yr conversation I speak of the dorsal fin of Mollienesia Petenensis as occellated with bright spots; but you in the Zoolog. Trans. merely speak of a "row of large rounded spots" Which of these is correct?

(2) Agassiz writes to me that certain Chromids, as Pomotis, Hygrogonus &c sit on their nests; do you happen to know whether it is the male, or the female, or indifferently both sexes, which thus sit?

[1v]

(3) I understand you to say that the female of Solenostoma is brighter coloured than the male; is this the case, for you do not say so in the Fishes of Zanzibar? Do you believe Kaup's statement that the males have marsupial sacks & carry the eggs? What must I say on this head?

(4) Is it known whether any Lizards utter any sound during their courtship?

(5) you gave me cases, with Lizards, of the dorsal crest being confined to the males; &

other cases in which the crest was larger in the males than in the female;

[B15]

Now are there other cases in which the dorsal crest is equally developed in both sexes?

(6) Chamælio bifurcus. What is its native Country? Is it brightly coloured, especially the projections on the head of the male?

(7) Chamælio owenii. What is its native Country? Is it brightly coloured?

Has the female any rudiment of the triple horn? Is the horn in the male flexible or rigid?

Is the triple horn formed by the modification of one or more scales?

[B15v]

(8) Can you remember whether any amphibian or reptile is marked with true ocelli of bright colours; that is a spot of colour surrounded by a ring of another colour?

Ch. Darwin. [crossed]

(9) With Lizards are the males generally or often or rarely larger than the females?
