REPORT ON ZOOLOGY, MDCCCXLII : 
the size of millet-seed and nuts, together with numerous small and larger 
pieces of bone sticking to the inner wall of the sac ; small sacs of the 
same kind were situated on the pubis, ischium, and coccyx. The blad- 
ders were partly free and partly united, particularly the small ones, or 
several were together in the dilated pores or cells of the bare and 
much shattered bone ; the head of the thigh-bone projected into an ace- 
phalocystous sac, occupying the place of the socket, which was completely 
eroded. This case has also been related by Robert (Oppenheim’s 
Zeitschr. f. die Gesam. Mediz. Bd. 20, p. 92). 
Reginald James mentions the case of a man, fifty-nine years old, 
in whom the lateral section of the bladder was made for a retention of 
urine (I^ond. Med. Gaz. Oct. 1842, p. 151). A considerable quantity of 
urine escaped, without reducing the swelling of the pubis or the pain of 
the patient. After death, a swelling was found behind and above the 
bladder, filled with hydatids of different size, and which had pressed it 
so close to the pubis, that it was divided into an upper and under por- 
tion, the latter of which only had been opened in the operation. Another 
case of Echinococcus hominis has been communicated by Koch (Ro- 
hatzsch. aUgem. Zeit. f. Chirurg. 1842, No. 17). 
Schiodte has found an intestinal worm in the stomach of Opatrum 
sahulosum of half a line long, which seems allied to the CaryophyllcBus, 
and resembles the figure of a parasite, given by Leon Dufour, in the 
Ann. d. Sc. Nat. 1826, pi. 21, bis, fig. a.-d. (Kroyer, Naturh. Tidsskr. 
Bd. 4, p. 208). That animal, therefore, certainly does not belong to 
Caryophyllceus, but to the enigmatical form of the Gregarina, which 
are probably subject to a transmutable generation. 
HELMINTHES GENERIS BUBII. 
Oersted mentions a sagittal-shaped Hehninthis, which he found in the 
intestinal canal of Lumhriconais marina, Oerst. (Kroyer, Naturh. 
Tidsskr. Bd. 4, p. 133). Although a figure is given of the animal, yet the 
reporter does not know what to make of it. Nor can he make any thing 
of another enigmatical parasite, which Kroyer discovered on the abdomen 
of Hippolyte pusiola (Monografisk Fremdstillmg af Slaegten Hippolytes 
nordiske Arter med Bidrag til Dekapodernes Udviklingshistorie. Kjoben- 
havn, 1842, p. 56). The structure is very simple, and points out its 
position between the Lerncece, Hirudines, and Helminthes. 
Philippi asserts, that the Physophora harbours in its stomach, worms 
which as yet have not been clearly defined (Fror. N. Notiz. Bd. 23, 
p. 88, and Bd. 22, p. 344). 
A vermicular disease of poultry has been mentioned by Delafond, 
without exactly describing the worms (Gurlt und Hertwig’s Mag. ant. cit. 
p. 115).
