263 Part III.—Seventeenth Annual Report 
(fig. 9, Pl. XII.). The mandibles are long and slender (fig. 10, Pl. XIT.). 
Figure 10a represents the apical portion of oue of the mandibles greatly 
enlarged, which somewhat resembles the apical portion of the mandibles in 
Bradypontius magniceps (Brady). The maxille resemble very closely 
those of Dyspontius striatus, Thorell, but the inner lobe is slightly longer 
than the outer, and the terminal setze appear to be shorter than those of 
the maxille of that species (fig. 11, Pl. XII.). The first joint of the 
anterior foot-jaws is large and robust, but the second is elongate and 
slender, somewhat dilated at the extremity, and armed with a short, 
stout, and finger-like subapical claw (fig. 12, Pl. XII.). The posterior 
foot-jaws have the first and second joints moderately robust, but the 
end joints are somewhat slender, and terminate in a short, stout claw, as 
shown in the figure (fig. 13, Pl. XI.) 
In the first pair of swimming feet, which are moderately stout, the 
outer and inner branches are nearly of equal length. The outer branches 
are armed exteriorly with short, stout, dagger-like marginal spines, and 
the interior marginal sete are one on the second and five on the last 
joint. The inner branches are furnished with one seta on the inner 
margin of the first joint, and two on the second joint ; while the third 
joint has five setee on the inner margin and apex, and a small one on the 
outer margin (fig. 14, Pl. XII). 
In the fourth pair the outer branches are stout and elongate; the 
first and second joints have each one marginal seta; the third joint 
bears five marginal sete, and is also armed with a moderately large 
sabre-like terminal spine in addition to the small spines on the outer 
margin ; the inner branches, which are three-jointed, and scarcely reach 
to the end of the second joint of the outer branches, are slender, and 
provided with only a few minute hairs on the margins and two small 
apical spines (fig. 15, Pl. XII). 
Fifth feet small, one-jointed, subquadrate, each of them furnished with 
one small marginal and two short apical sete. There is also close to 
each foot exteriorly a long seta with a slightly dilated base which 
springs from the edge of the segment to which the fifth feet are attached 
(ios Zils tele exalia): 
Habitat.—Firth of Forth. Rare. No males observed. 
Remarks.—As already stated, this specimen was first partly described 
and figured in the Appendix to the Sixth Annual Report of the Fishery 
Board for Scotland, published in 1888. It was described under the 
name of Artotrogus papiliatus, but some doubt was expressed as to its 
being a true Artotrogus. No more specimens having been observed, the 
interest in the species passed away, and it was practically forgotten. 
Recently, however, my son got hold of the original specimen from which 
the species was described, and with the assistance of Dr. W. Giesbrecht’s 
work on the ‘ Diagnosis, Synonymy, and Distribution of the Ascomy- 
zontidee” made a careful examination of the characters by which the 
species is distinguished, as well as a series of delineations illustrating its 
principal appendages. ‘The description given above is the result of this 
extra research, From the additional information that has been obtained 
by this re-examination, there can be no doubt that our species is a true 
Bradypontius. It agrees perfectly with Dr. Giesbrecht’s definition of 
that genus. It may also be identical with the species described by Dr. 
Giesbrecht under the name of Bradypontius chelifer from the Bay of 
Naples, and, if so, the distribution of the species will be very considerably 
extended. :
