Pkpsdcr madt'pcephalus, Mr. J, H. Thomson states that the frequent cases 
of deformity of the lower jaw (see ZooL Record, ii. p. 49) are found in male 
examples only, and caused by their mode of fighting, which is with their 
jaws mostly, Proc. Zool. Soc. 1867, p. 246, -^The same malformation iS 
also noticed and figured by Fischer in Robin, Journ. Anat. et Phys. 1867j 
p. 382, pi, 13. 
PhyseUr simus. A note by Sir W, Elliot with regard to a faulty figure of 
this species is published in Trans, ^ool. Soc. vi. pp. 171-174. See Zool. 
Record, iii. p. 40, footnote. 
"^ZipMus, M. P. Fischer describes the remains of Z. cavirostriSf 
Nouv. Arch. Mus. iii, pp. 41-78, pi. 4. On this occasion he 
enters int^ a critical revision of the existing and fossil Ziphioids 
generally, considerably reducing the number of genera and spe- 
cies established by authors. With regard to recent forms : — 
1. Cuvier's genus Zifhius comprises four species only, viz. Z. cavu 
rostris (Cuv.), Z.gervaisii (Duvern.), Z. indicus (Van Bened.), and 
Z. cryptodon (Burm.). 2. Hyperoodon (Lacep.) ; the author 
considers H. latifrons (Gray) and H. philippii (Cocco) to be pro- 
bably founded on old and young individuals of //. butzlwpf* 
3. Berardius (Duv.). 4. Mesoplodon (Gerv.) with M, sower- 
byensis (Blainv.), M. europatus (Gerv.), M, densirostris (Duv.), 
and M. layardi (Gray). ' 
Mesoplodon sowet'hiensis. M. van Beneden figures the lower jaw of an ex- 
ample found on the coast of Norway, and enumerates the remains of the 
species preserved in the various museums. Bull. Ac. Sc. Lett. Belg. xxii. 
1866, pp. 218-221. — A specimen cast ashore on the coast of Kerry (Ireland), 
Ann. & Mag. Nat. Hist. 1867, xix. p. 304 ] on the same example, W. An- 
drews, Proc. Roy. Ir. Acad. x. 1867, p. 61. 
•4 Epiodon patachonicum [quaere, us ?] is the name proposed now by Prof. 
Biumeister for his Ziphiorhynchus cryptodon, Zeitschr. ges. Ntrwiss. xxix. 
p. 6. He describes the skeleton, and explains, on this occasion, the asym- 
metrical structure of the nasal opening in this species and other Delphinoids 
by the presence of the large air-sac, which gradually pushes the nasal opening 
towards the left side. 
^ Inia geqffrensis. Mr. Flower has given a most detailed description of this 
Cetacean, Trans. Zool. Soc. vi. 1867, pp. 87-106, accompanied by excellent 
figures, pis. 26-27. 
'■^Pontoporia hlainvilUi. The skull is described and figured by Flower, 1. c. 
pp. 106-109, pi. 28.-^Dr. Burmeister has published a preliminary description 
of the skeleton, tongue, larynx, and stomach of this Cetacean in Proc. Zool. 
Soc. 1867, pp. 484-489. On the same subject in Zeitschr. ges. Ntrwiss. xxix. 
pp. 1 & 402. 
Delphmus. Prof. Burmeister has published remarks on the species in th^ 
Museum of Buenos Ayres, Zeit^cht. ges. Ntrwiss. xxix. They refer to DeW 
phinus mtcrops, p. 2, which he regards as identical with D. walkeri (Gray), 
I), ohscurus, p. 3, D. eurynome and 2). spimpinhis, p. 4. 
Delphinus delphis. Prof. Reinhardt reports on ah example obtained on the 
eastern coast of Jutland, and figures it. Vid. Meddel. naturk. Foren. Kjobenh.
