This term is applied to an ECHINORHYNCHUS found by Lambl in the intestine 

 of a boy who had died of leucamia; the worm was 5'6 mm. in length, and the 

 almost spherical head was beset with twelve transverse rows of hooks. 



wx Echinorhynchus moniliformis, Bremser, 1819. 



The male is 4 cm. in length, the female 8 cm. long. This species lives in the 

 intestine of field-mice, rats, marmots and Myoxus quercinus. A beetle (Blaps 

 mucronata) is the intermediary host. 



This species has also once been artifically cultivated in man (Grassi and 

 Calandruccio).
