200 THE SPOROZOA 



sub-family, and from the morphological point of view is intermediate 

 between the simple epimerite of Doliocystidae and the more complex 

 epimerites of Actinocepkalidae (Leger). Genus 45. Asterophora, Le"ger, 

 1892. Epim. composed of a circular ridge with radiating rib -like 

 thickenings, surrounding a prominent central papilla. Protom. ordinarily 

 larger than the deutom. Sporonts solitary, of elongated form. Spores 

 cylindrical with conical extremities. A. mucronata, Leg., from the gut of 

 the larva of Rhyacophila, and A. elegans, Leg., from the digestive tract of 

 the larvae of Phryganea grandis and Sericostoma sp. Genus 46. Stephano- 

 phora, Ldger, 1892. Epim. large, in form of a convex disc bearing a 

 crown of finger-shaped tentacles. Spores as in the last. Unique species 

 S. lucani (Stein), from the gut of Dorcus parallelipipedus. Genus 47. 

 Bothriopsis, A. Schneider, 1875. Epim. in form of a lenticular knob 

 bearing long flexible non- motile filaments. Sporonts solitary, with 

 protom. greatly developed and very mobile. Spores biconical, obese. 

 Unique species B. histrio, A. Schn., from the gut of Hydaticus sp. 

 Genus 48. Coleorhynchus, Labbe", 1899 (nom. nov. for Coleophora, A. 

 Schneider, 1885, preoccupied). Sporont with protom. in the form of a 

 sucker or strawberry, extending over the deutom. ; septum convex, 

 projecting into the protom. ; deutom. subspherical or cylindrical. Spores 

 navicular. Unique species G. heros (A. Schn.), from the gut of Nepa 

 cinerea. Genus 49. Legeria, Labbe, 1899 (nom. nov. for Dufouria, A. 

 Schneider, 1875). Protom. dilated, club-shaped ; septum convex, pro- 

 jecting into protom. Spores subnavicular, with thick sporocysts. Unique 

 species L. agilis (A. Schn.), gut of larva of Colymbetes sp. Genus 50. 

 Phialoides, Labbe, 1899 (nom. nov. for Phialis, Leger, 1892, preoccupied). 

 Epim. in the form of a retractile boss, surrounded by a circular ridge 

 'and a collar-like membrane with pleats terminated by triangular teeth. 

 Sporonts massive, solitary. Spores biconical, obese. Unique species P. 

 ornata (L4g.), from the gut of the larva of Hydrophilus piceus. Genus 51. 

 Geneiorhynchus, A. Schneider, 1875. Epim. in the form of a disc bristling 

 with fine pointed teeth, carried on a very elongated neck (Fig. 17, </). 

 Spores subnavicular. Unique species G. monnieri, A. Schn., from the 

 gut of the nymph of Libellula. Genus 52. Actinocephalus, Stein, 1848. * 

 Epim. sessile or on a well-marked neck, and provided with hooks or 

 spines. Spores biconical. A. stelliformis, A. Schn., from the gut of 

 Ocypus olens and other beetles ; and other species. Genus 53. Pyxinia, 

 Hammerschmidt, 1838. Epim. in the form of a cup or saucer with 

 fringed rim surrounding a central spike (Fig. 15). P. rubecula, Hamm. 

 (Figg. 15 and 33), from the gut of Dermestes lardarius and D. vulpinus ; 

 and other species. Genus 54. Beloides, Labbe", 1899 (nom. nov. for Xipho- 

 rhynchm, Leger, 1892). Epim. in form of disc or knob furnished with 

 about ten teeth, and bearing in the centre a long spike (Fig. 17, e). Spores 



1 The two species mentioned by Stein (Miiller's Archiv, 1848) under the genus 

 Actinocephalus were A. acus, Stein, from Carabus glabratus and A. lucani from 

 Lucanus (Dorcus) parallelipipedus. The former of these is not mentioned in Labbe's 

 Sporozoa, the latter is placed, following Leger, under the genus Stephanophora, Leger. 

 These facts may necessitate a revision of the nomenclature of the genera of Actino- 

 cephalidae, since the genus Actinocephalus in Das Thierreich does not contain either 

 of the species placed in it by the founder of the genus.
