terior to cirrus-pouch. Ovary voluminous, lobes somewhat winglike. 

 Uterus possessing about twenty long outpocketings on either side. Eggs 

 provided with three membranes. Diameter of egg 0.024 mm. 



Habitat: In intestine of South American snakes of the family 

 Colubridae, subfamily Colubrinae. 



This species was first described by Rudolphi (1819 :692). Since this 

 description is not readily accessible to many workers it is quoted in full : 



"Taenia racemosa R. n. sp. Pone Synops. n. 52. 



"T. Capite obconico, collo brevi, angustissimo, articulis planis, elongatis, fora- 

 minibus marginalibus alternis prominulis. Hab. In intestinis Colubri n. 20. speci- 

 men sexpollicare et fragmenta hujus Taenia Natterer in Brasilia reperit. 



"Caput antrorsum dilatatum, sive obconicum, osculis orbicularibus, aut hemis- 

 phaericis, nam satis profunda videntur, anticis. Collum breve, angustissimum. 

 Articuli, quos vidi, plani, tenues, elongati, lineam ad sesquilineam longi, tertia 

 lineae parte latiores, foraminibus marginalibus alternis, prominentibus. 



"Ovaria singulorum articulorum lineam mediam fere totam sibi vindicant, ad 

 cujus latera utrinque maculae exiguae opacae ita digestae sunt, ut ovaria racemosa 

 appareant. 



"Obs. Caput Taeniae omphalodis Synops. n. 9. articuli vero T. tuberculatae n. 

 25. ut fragmenta, quae vidi, Taeniam illis intermediam reddant." 



Rudolphi (1819:709) established the name Taenia colubri to desig- 

 nate a few proglottids found in Coluber sp., Brazil by Natterer. His 

 exact words are here quoted : 



"Taenia Colubri. Pone Synops. n. 140. 



Fragmenta in intestinis Colubri n. 12. a Natterero in Brasilia reperta Museo 

 Viennensi debeo lineam circiter longa, duodecim ad octodecim articulis constantia, 

 latioribus quam longis, subcuneatis, angulis plus minus exstantibus, capite destituta. 



"Utrum vere colubrina, an ex ave quadam deglutita forsan residua?" 



Dujardin (1845:610) added nothing to Rudolphi 's description. 

 Diesing (1850:511) gave a short diagnosis of a form from the museum 

 at Vienna which he identified as Taenia racemosa Rud. His description
