which he thought might be B. musculus of Linnzus (it is not 
well copied by Bonnaterre, E. M. t. 3. f. 1, and Schreber, t. 335), 
which has a large pectoral fin, about 3 the length of the body ; . 
but the drawing is not so good as the others in the work, and the 
fin is so awkwardly applied to the body, that perhaps its size 
may depend on the incompetence of the artist. The dorsal fin, 
which is only indicated as if doubtful in the original a is 
continued to the tail, but in Bonnaterre’s copy it is represented 
as of equal authority with the other part. 1 
Fabricius (Faun. Gren. 37), five years after, described a Bale- 
noptera under the name of B. Boops, Linn., which appears to 
differ from B. Physalus, for he described the “ Pinne pectorales t 
magne, obovato-oblonge, margine postica integra, regione cubiti 
parum fractz, antica autem rotundato-crenate.” And, he con- 
tinues, “‘ Ante nares in vertice capitis tres ordines convexitatum 
circularium, huic forsitan peculiare quid,””—‘ Pinna dorsalis com- 
pressa, basi latior, apice acutiuscula, antice sursum repanda, 
postice fere perpendicularis,” and “ Corpus pone pmnam dorsa-— 
lem incipit carma acuta in pmmam caudalem usque pergens.” 
Rudolphi, and after him Schlegel, refers B. Boops, O. Fabri- 
cius, to this species; and Professor Eschricht has no doubt that 
Balena Boops of O. Fabricius is mtended for this species, as it is” 
called Keporkak by the Greenlanders. If this is the case, Fabri- 
cius’s description of the form and position of the dorsal fin, and 
the position of the sexual organs, is not correct. E 
Brandt, in the list of Altaian animals (Voy. Alt. Orient. 1845, 
4to), has adopted this opinion, and formed a section for Baleno- 
ptera longimana, which he calls Boops, merely characterized as 
‘* Pectoral elongate.” q 
Schlegel refers the Rorqualus minor of Knox to this species, 
probably misled by the inaccurate figures of this species im Jar- 
dine’s Nat. Lib. vi. t. 6. See note on this figure under Balenos 
ptera rostrata, p. 33. 
Schlegel pomts out that Rudolphi and M. F. Cuvier, in thei 
description of B. longimana, have confounded the figure of Baleine 
du Cap and Rorgual du Cap, of Cuvier’s Ossemens Fossiles, 
together.— Faun. Japon. 21, note. 4
