98 REPORT—1863. 
but the imperfect state of which had been described by Dr. Johnston as a Lepralia 
(this was found on the coast of Northumberland, by Mr. Embleton) ; Quadricellaria 
gracilis of Sars, previously published from an imperfect specimen under the name 
of Onchopora borealis by Professor Busk. Scrupocellaria Delilii, a species new to 
Britain, was got from the deep-water fishing-boats on the coast of Northumberland 
by Mr. Alder, and has since been dredged on the Durham coast. The last species 
described was the Hornera borealis of Busk, which is now introduced as British for 
the first time: specimens of this were got in Shetland by Mr. Barlee in 1858, and 
since by Mr. Norman. The paper was illustrated by drawings; and specimens of 
most of the species were exhibited. 
On a New Species of Ione. By C. Spence Barz, F.R.S. 
The genus Jone was first established by Col, Montagu, to receive a species of 
parasitic isopod Crustacea, allied to Bopyrus, which he found beneath the carapace of 
Callianassa subterranea, a variety of prawn that burrows beneath the sand, and is 
found at the entrance of Salcombe Estuary, as well as in Plymouth Sound. This 
rawn has likewise been taken on the coast of France, and the parasite described 
y Milne-Edwards. The new species, which the author has named Jone cornutus, 
was brought home by Mr. Lord, the naturalist to the Commission which had to 
determine the boundary-line between British territory and that of the United States, 
and was found parasitic upon a species of Calhanassa which he took on the coast 
of Vancouver’s Island. is species is much larger than that of the European 
form, and differs from it chiefly in having the lateral extremities of the somite, or 
segment which bears the antenne, posteriorly produced upon each side of the head, 
after the manner of lateral horns. All the perelopoda are short and powerfully sub- 
chelate. The branchial appendages are arborescent and pendulous; to the inner 
extremity of which two appendages are attached, each of which inversely increases 
as the other decreases; so that one is largest nearest the pereion of the animal, 
while the other is longest nearest the caudal extremity. To the posterior of 
these the male animal attaches itself by means of the seventh pair of pereiopoda. The 
author likewise remarked a very considerable variation in the form of the larvae 
from that of either of the parents, although it more nearly corresponded with that 
of the male than with that of the female. 
On the Syndactylous Condition of the Hand in Man and the Anthropoid Apes. 
By C. Carrer Braxz, F.G.S., Hon. Sec, ASL. 
The author called the attention of the Section to a curious abnormity which is 
resented by the integument of a specimen of old male Gorilla which was brought 
Bae the Gaboon by Mr. Winwood eade, and presented by that gentleman to the 
Museum of the Anthropological Society of London. The specimens of Gorilla 
‘which have been the subjects of the elaborate and complete memoirs which have 
appeared from the pen of MM. Duvyernoy and Isidore Geoffroy St.-Hilaire in the 
Archives of the Paris Museum (vols. viii. and x.), and by Professor Owen in various 
parts of the ‘ Zoological Transactions,’ have, with those described by other authors, 
all coincided in one attributed character, true as regards the specimens with which 
they were acquainted, which probably represent the majority of specimens of Gorilla 
which had been examined in Europe. This statement, reduced to a general pro- 
position, was that the integument of the skin of the fingers was more or less con- 
nected across the first digital phalanx, in such a manner that the first joints were 
firmly connected together by skin, sometimes as far as the distal extremity of the 
first phalanx, sometimes merely to the middle of this phalanx. In no specimen of 
Gorilla, of the description of which the author is yet cognizant, are the digits of the 
anterior extremity free to the same extent as in man, in which the distal extremities 
of the metacarpals mark the termination of the amount of syndactyly of the hand. 
In the specimen of Gorilla to which allusion is made in this short note, the digits of 
the fingers present a different condition of connexion from that in the typical speci- 
mens described by zoologists. The second (index), third (medius), and fourth 
(annulus) digits are free beyond the distal end of the metacarpals, as in the human 
subject; the fifth digit (minimus) is also in a less degree attached to the annulus
