these fish exercising their skill in shooting at the fly with an 
amazing velocity, and never missed the mark.” 
Then follows a description of Chetodon rostratus of Linneus 
(Mus. Ad. Frid., 1754, p. 61, t. 33), as being the species alluded 
to, the tubular-mouthed fish that knocked down insects at a 
distance of several feet by discharging at them a single drop 
of water. To obviate any misconception, a figure is given at 
plate ix., which is the fish alluded to, identical with Linneus’s 
C. rostratus. (See fig. 1 opposite). 
In volume fifty-six of the same ‘ Transactions,’ p. 186, occurs 
“Some further intelligence relating to the Jaculator-fish, mentioned 
in the ‘ Philosophical Transactions’ for 1764, Article xiv., from 
Mr. Hommel at Batavia, together with the description of another 
species by Dr. Pallas, F.R.S., in a letter to Mr. Peter Collinson, 
F.R.S., from John Albert Schlosser, M.D., F.R.S.” 
Here the account of the Jaculator is continued, and Mr. 
Hommel remarks :—‘‘ With the closest attention I never could 
see any part of the mouth out of the water, though I have very 
often seen the Jaculator fish shoot a great many drops one after 
another, without leaving its place and fixed situation. No more 
than two different species of this fish are found here. The first 
and rarest kind is that which I sent before; and to the description 
published in the fifty-fourth volume of the ‘Philosophical Trans- 
actions’ the foregoing account may be added. You will now 
receive from me a specimen of the second species, which is the 
most common here.” 
A figure of this second species, termed Sciena jaculatriz, is 
added (see fig. 2 opposite), leaving no doubt as to its being the fish 
now known as Toxotes jaculator, but to which the foregoing account 
does not refer, as expressly observed. While Pallas, in his ‘ Spici- 
legia’ (1770, fasciculus 8, p. 41), when alluding to this second form, 
or Sciena jaculatrix, which he terms “ Scienis vel Sparus,” very 
properly omits all suggestion as to its being endowed with 
shooting propensities, because such were not attributed to it by 
Hommel or Schlosser. 
Pallas in his ‘ Spicilegia,’ J. c., figures a third form (see fig. 3 
opposite), which he terms Sparus insidiator, and also attributes 
to it the same habit of shooting insects as was assigned to 
Hommel’s first fish. He adds a figure which most unquestionably 
refers to an EH pibulus, as observed by Cuvier and Valencienne (vol.
