served on a whaling-expedition in the Iceland Sea : Vid. Med- 
del. ntrh. Foren. i Kjdbenh. for 1867 (1868), pp. 150-177. 
They refer chiefly to Balaenoptera ; and especially to the Stey- 
pireyor of the Icelanders, which formed the subject of Prof. 
lleinhardPs paper noticed in Zool. Record, v. pp. 9 & 26. 
'I Mr. C. M. ScAMMON has published the results of many years^ 
observations made by him whilst engaged in the whale-fishery 
on the western coast of North America (Proc. Acad. Nat. Sc. 
Philad. 1869, pp. 13-63). The paper, which contains some de- 
scriptive details, treats chiefly on peculiarities and habits of the 
various Cetaceans distinguished by whalers, and on the mode of 
capture. Mr. Cope, who edited the paper, has prefixed a 
systematic synopsis, in which the species observed and men- 
tioned by Mr, Scammon, and others known to exist in those 
parts, with the addition of some Atlantic Cetaceans, are cha- 
racterized. The following are mentioned or described in this 
paper : —

'"^Agaphelus is the name of a new genus proposed by Mr. Cope for Balcena 
gibbosa (Erxl.) and the Grey Whale of California, Agaphelus glaucus (Cope).

former species and notes on the latter, ibid. p. 221. — A. glaucus made 
the type of a distinct genus, Rhachianectes^ ibid. 1869, p. 16, figs. 7-8. 
d Balcenoptera, Four species only inhabit the North Atlantic, according to 
Prof, van Beneden, Bull. Ac. Roy. Belg. xxvii. 1869, p. 281 ; they are : — 1. 
B. rostrata (Fabr.) ; 2. B. borealis (Cuv.) = laticeps (Gray) ; 3. B. musculus 
— Physalus antiquorum (Gray) = B. gigas (Eschr.) ; 4. B. sibbaldii (Gray) 
= latirostris (Flower) = carolince (Malm). The author adds the principal 
specific characters and a list of the specimens observed, and shows on a map 
the localities where each species has been found. 
Baleenoptera musculus. Prof. Flower has described and figured an example 
stranded on the south coast of England in 1869 (Proc. Zool. Soc. 1869, 
p. 604, pi. 47) ; he has also appended notes on three other skeletons of the i 
same species, showing variations in the development of the lower transverse 
process of the sixth cervical vertebra, in the presence or absence of the capitular
