454 REPORT ON ZOOLOGY, MDCCCXLIV. 



The Reporter will recur more at length, below, to a case 

 of disease described by Goodsir, in which he states that he 

 observed Filarite associated with cystic bodies. C. H. 

 Schmidt has given a short notice respecting numerous 

 Filarire, between the coats of the intestine of the larva of 

 Bombyx dispar. (Amtlicher Bericht iiber die zwei und 

 zwanzigste Versammlung deutscher Naturforscher und 

 Aertzte in Bremen iin September ]844. Abth. ii, p. 129.) 

 llayer (Archives de Med. comp. 1. c. p. 171, pi. 8, figs. 1-9), 

 who, together with Desir, examined many Dogs, found in 

 one of them, between the muscular coats of the oesophagus, 

 a tumour of the size of an almond, with thick walls, which, 

 besides pus and blood, contained several convoluted worms. 

 These presented all the characters of Spiroptera sanguino- 

 lenta, a worm found by Rudolphi, only in the Wolf. Valen- 

 ciennes (Comptes rendus, 1843, p. 71 Sur des tumeurs 

 vermineuses de Festomac du cheval, et sur les entozoaires 

 qu'elles contiennent) has met with two different worm- 

 tumours in the pyloric extremity of the stomach and in the 

 colon of a Horse. One sort of these tumours is inhabited 

 by a solitary Stronffylus, in the other were contained several 

 worms altogether different. The first verminous tumour 

 occurred to him at the end of May, in a lame, but in other 

 respects healthy horse, in which it formed a small projec- 

 tion on the inner surface of the stomach. He afterwards, 

 in eleven instances out of twenty-five horses, met with 

 similar tumours, which were imbedded between the mucous 

 membrane and fibrous coat of the stomach, and discharged 

 themselves on the internal surface of that viscus by one or 

 several openings. The cavity of this kind of tumour was 

 surrounded by a very thick fibrous wall, and divided by 

 septa into several compartments, all of which, however, 

 mutually communicated, and were filled with a tenacious 

 mucus, in. which numbers of small nematoid worms were 

 always enveloped and entangled. Male and female indi- 

 viduals could be distinguished among them. Their mouth 

 presented no distinctive character, the caudal extremity of
