ScOMBRESOCIDiE. 
Hemirhamphus. Dr. Bleeker lias revised the speeies found in 
the East-Indian Archipelago (Nederl. Tydschr. l3ierk. iii. 1865, 
pp. 136-170). lie describes nineteen species, adopting the ge- 
neric divisions proposed by Mr. Gill, and defining another, 
Hemirhamphodon, for H. phceosoma and H. pogonognathus. We 
notice the following species described as new, or because we 
cannot quite agree with the author with regard to their syno- 
nymy :~H. cantoris y sp. n., p. 145 [is not = H. georgii (Cant.) as 
stated by the author ] ; balinensis (Blkr.) is stated to be iden- 
tical with H. intermedius (Cant.), p. 154 [this does not prove to 
be the case];^^. melanurus (Blkr.) is certainly not the species 
described by Valenciennes, but, in our opinion, identical with if. 
gaimardi (Blkr.; an C. & V.?); H. neglectus described as a new 
species, p. 157 [is identical with the Atlantic H. unifasciatus = 
H, richardi ] . ^ 
Hemirhamphus Jluviatilis and Hemirhamphus viviparus, sp, n, [?], from the 
island of Samar, are viviparous. Peters, Monatsber. Akad. Wiss. Berl. 1865, 
p. 132. 
Exoccetus. Dr. Bleeker has reexamined the species of his 
collection and gives comparative descriptions of them, distin- 
guishing several new forms (Nederl. Tydschr. Dierk. iii. 1865, 
pp. 105-129) : — E. oUgolepis, p. 109 ;^E. brachysoma, p. Ill ; 
E. neglectus, p. 112 ;E. spilonotopterus , p. 113 [is identical with 
E, bahiensis from the Atlantic] katoptron, p. 115; and^^. 
opisthopus, p. 121. He proposes the generic nomS Parexocoetus 
for E. mento and allied species, p. 126. 
Exocoetus polleni is described as a new species by Bleeker, 1. c. p. 130, from 
the Atlantic. He describes also’*^^. bicolor, p. 132. 
Exocoetus californicus, sp. n.. Cooper, Proc. Calif. Ac. Nat. Sc. iii. p. 93, 
fig. 20. We notice this species again, because it was misplaced by an over- 
sight in our last Becord, where it should stand on p. 177, and not on p. 183. 
EsociDiE. 
Prof. Cope has given a descriptive sjmopsis of the American Pikes, adding 
a new species,^ cypho from Michigan. Proc. Ac. Nat. Sc. Philad. 1866, 
p. 78. 
SALMONIDiE. 
Salmo lacustris [schiffermulleri ) . Prof. Kner states it as the 
opinion of a fisherman, that this fish (Mui-Forclle) is a hybrid
