foundcfl are of siibgoneric value only. The gill-cavities of several of the 
species are figured. Overs. Oansk. Vid. Selsk. 18G5, pp. 95-112.

Rhomhoidichthys. ^ Dr. Bleeker describes three new species from the East- 
Indian Archipelago: Platophrys polyopthalmm, I, c. p. 46 ; P. intermediuSj p. 47 ; 
. an d^P. tapehiosoma, p. 49. 
Soha heterorhinp, var. , is described and figured by Kner, Denkschr. Ak. 
Wiss. Wien, xxiv. taf. 3. fig. 2. 
SoleotaJpa unicolor. Dr. Bleeker describes and figures, under the name of 
Apionichniys dumerilii (Kaup), a specimen which evidently belongs to Solco- 
talpa. Nederl. Tydschr. Dierk. ii. 1865, pp. 306-308. Whether the species 
is identical with S. unicolor remains uncertain without examination of more 
materials. The eyes of Dr. Bleeker’s specimen are much more approximate 
to each other than in S. unicolor ; and a connecting membrane extends from 
dorsal and anal to caudal, entirely absent in S. unicolor ; yet the number 
of the fin-rays is nearly identical in both fishes. Dr. Bleeker believes 
that SoleotaJpa is identical with Apioyiiclithys (described as having the verti- 
cal fins united like Synapiurd) : if this opinion should prove to be correct, 
the species would stand, at all events, as Apioniclithys unicoloVy and not as 
A. dumerilii, a name never accompanied by a diagnosis, and therefore not 
acceptable to zoologists who care about justice in scientific work.

Pseudeutropius mitchelli. Although Mr. Day states (Fish. Malabar, 
p. 192) that he has no doubt Mr. Jerdon described his ScliiWcsykcsiiiieomfm 
example without adipose fin, it must, even in that case, appear doubtful 
whether the fish is identical with P. mitchelli. If he cannot verify his 
assertion by the examination of the typical specimen, he has no right to 
exchange the name of a well-determined species for that of a doubtful one.

Pimelodus cinerascens. The species described by Kner and Steindachner 
(Verhandl. Bayr. Ak. Wiss. x. 1, p. 49) is probably not identical with 
P. cinerascens (Gthr.). The original description of the latter (designated as 
^^00 short” by those writers), accompanied by an excellent figure, points 
out sufficiently all the characters by which allied species may be distin- 
guished. 
Pimelodus haronis mulleri is described as a new species by Troschel, in 
Muller, Wirbelth. Mex. p. 102, from the Pacific coast of Mexico. 
Arius multiradiatus (Gthr.) ^Bagrus(^) arioides is described by Kner and 
Steindachner, Abhandl. Bayr. Ak. Wiss. x. 1, p. 47.
