This is the species originally described by Girard (doe. cit.) under 
the name rosaceus, and again quite correctly in the tenth volume of 
the ‘Pacific Railroad Reports.’ In this latter publication he incor- 
rectly refers my Sebastes ruber to it asasynonym. The two are 
widely distinct : S. rwber has the top of the head strongly ridged and 
spinous, as already stated in this present communication ; S. rosaceus, 
as its generic affinities indicate, has the same region almost entirely 
smooth, the nasal and occipital spines being barely discernible: in 8. 
ruber the preopercular spines are blunt, almost truncated ; in S. rosa- 
ceus the same spines are long and very sharp : in S. ruder the anal fin 
is small and rounded, its height being only about one-eighth of the 
length of the fish, while the second and third spines of the fin are 
nearly as high as the soft portion ; in S. rosaceus the same fin is much 
larger and pointed, its height being more than one-sixth of the length 
of the fish, while the third anal spine (which is higher than the 
second) is only about half as high as the soft portion. Many other 
points might be noticed, but these are sufficient. The outline figures 
show very clearly the relations of the two species. 
Sebastodes rosaceus is quite common. It is a smaller fish than 
Sebastes ruber, seldom exceeding five or six pounds in weight. 
The eleven species thus indicated are brought to the markets of 
San Francisco at all times of the year, the fishery being little affected 
by the seasons. They are taken with the hook, in the open sea, near 
the Bay of San Francisco, wherever rocky bottom is found. One 
species only, Sebastes auriculatus, is caught about the wharves of the 
city. The spawning-season is from March to June; and in all the 
species the development of the young takes place within the body of 
the mother, but to what degree I have not yet the means of stating 
with absolute accuracy. I have traced them to such a stage of ad- 
vancement that the mouth, the intestinal canal, the vertebral divi- 
sions, and the vertical fins were all plainly discernible, and of course 
the eyes strongly marked and prominent, the embryo on being re- 
moved from the egg being fully half an inch in length. 
Nores on THE Kacu. By Dr. GeorGe Bennett, F.Z.S. 
On the 13th of June 1863, I received from New Caledonia, by 
H.1.M. Schooner ‘ La Calédonienne,’ a pair of Kagus (Rhinochetus 
jubatus), male and female—one presented to me by-Dr. Segol, the 
surgeon of the vessel, and the other obtained and sent to me by the 
kind exertions of M. Ferdinand Joubert, now residing in New Cale- 
donia. Both these gentlemen have been indefatigable in endeavour- 
ing to procure living specimens, the value of which is much raised 
by the increased scarcity of Kagus on the island. The day following 
their arrival I placed them in the aviary in the Botanical Gardens. 
The female is a fine bird, and the largest specimen of the Kagu I 
have yet seen. It is graceful and elegant in appearance, active and 
lively in its habits, and its plumage in excellent condition. It is 
distinguishable from the male bird by its much larger size, and by 
the light colour of its plumage, also of its bill, feet, and legs. She 
has besides a peculiar habit of crouching on the ground and covering 
herself with her wings, by throwing them over together in a concave
