Miscellaneous. 
of course, the species described by Mr. G. Browne Goode in 1874 as 
Din [derm Lefroyii did not escape my notice, but that I considered and 
still consider the fish sent by Mr. Matthew Jones to the British Museum 
to be distinct, as it differs in the number and proportions of the anal 
spines from Mr. Browne Goode’s fish. The character mentioned is 
one of considerable weight in the determination of the fishes belong¬ 
ing to the genus Gerres; and therefore I am not yet inclined to 
unite the two species, as Mr. Browne Goode appears to have 
done, if he was really in possession of two- as well as three-spined 
specimens. 
With regard to Belone Jonesii 1 admit that I was not acquainted 
with Mr. Browne Goode’s description published in 1877 ; and it is 
a very fortunate circumstance that we both happened to choose the 
same name. 
I may mention, in palliation of this my oversight, that the report 
on fishes for that year in ‘ The Record of Zoological Literature ’ was 
not published at the time of the publication of my description, and 
that I am only one of the numerous victims who suffer from the 
tardiness of publication into which that work has been allowed to 
fall. 
On the Presence of a Segmental Organ in the Endoproct Bryozoa. 
By M. L. Joliet. 
In October 1877 Hatschek indicated in Pedicellina echinata , both 
in the larval and adult state, avibratile canal, of which, however, he 
seems not to have well made out the form, and which he compares 
to the vibratile organs of the Rotatoria. I am in a position to con¬ 
firm the statements of the zoologist of Prague, at the same time 
correcting and completing them, and to extend them to the whole 
group of Endoproct Bryozoa. 
In a spineless variety of Pedicellina echinata which abounds at 
Roscoff, whence the keeper of the laboratory sent it to me alive 
within the last few days, the vibratile organ is double, and situated 
in the cavity of the body, in the space included between the oeso¬ 
phagus, the stomach, and the matrix. 
It consists of a short tube, ciliated internally, inflated at its 
middle, which, on the one hand, opens into the matrix, not far from 
its external aperture, and, on the other, opens obliquely into the 
cavity of the body by a slightly funnel-shaped passage furnished 
with active vibratile cilia. This organ, furnished with a vibratile 
pavilion, and placing the cavity of the body in communication with 
the outer world, has all the characters of a segmental organ. It 
appears very early in the bud. When the stomach is only sketched 
out, and before the arms are indicated, we already see a ciliary 
movement at the place that it will occupy. 
In a still undescribed species of Pedicellina from the island of 
St. Paul, I have recently detected the same vibratile organ. Lastly, 
in the Lo.vosoma of Phascolosoma, 1 last summer, at Roscoff, recog-
