Pisces 22 
I Cluj)m tyrannus, Latrobe. Clupea menhaden, Mitch., is undoubtedly 
this fish, which should, therefore, be called Brevoortia tyrannus. Some 
remarks on the species ; G. B. Goode, P. U. 8. Nat. Mus. i. pp. 5 & 30 J

Clupea pilchardus and sprattus figured, with air-bladder, stomach, and

'xclimatal variety of C. sprattus. Day, P. Z. S. 1879, p. 759, pi. Ixii.

Bathythrissid.®. 
[See Zool. Rec. xiv. Pisces, p. 28.] Bathythrissa dorsalis, Gthr., = 
Pierothrissus gissu ; Hilgendorf, Leopoldina, xiii. p. 127. The writer 
regards it as questionable whether the absence of the oviduct is sufficient 
to constitute it a distinct family. On* account of its close affinity to 
Alhula, it may eventually be united with that genus as a separate family, 
or ranged among the Clupeidce. Hilgendorf, SB. nat. Fr. 1878, p. 156. 
Gymnotid.®. 
Gymnotus electricus. C. Sachs, in his work, “ Aus den Llanos,” above 
mentioned (p. 6), describes the habits and electrical apparatus of this 
species, especially in Chapter V., pp. 133-171. He figures it, p. 149, and 
a section of its body showing the electric organs, p. 154. An analysis 
of his observations is given in J. de I’Anat. 1879, p. 614. See also
