184 STRONG YLOIDE A 



very dissimilar in size. Extemo-dorsal rays about as long 

 as the lateral rays. Dorsal ray long, fairly stout, cleft at its 

 tip, with two pairs of small accessory branches and a number 

 of short terminal digitations. Spicules distinctly bifurcate, 

 but of complex structure, with multiple terminations. Acces 

 sory piece absent. Eggs contain embryos when deposited. 



Hab. Intestine and lungs of Reptiles and Batrachians. 

 Genotype : 0. [Stro7igylus] subauricularis (Rudolphi, 1819).

12. Molineus Cameron, 1923. 



Cuticle of anterior end inflated and transversely striated. 

 Cervical papillae absent. Bursa not distinctly divided into 

 lobes. Ventral rays long and parallel, but slightly separated 

 distally. Antero-lateral ray about half the length of the 

 other lateral rays and somewhat divergent from them. 

 Externo-dorsal rays considerably shorter than the postero- 

 lateral and medio-lateral rays, not reaching the margin of 

 the bursa. Dorsal ray bifurcate at its tip, each branch 

 ending in three short digitations. Prebursal papillae absent. 

 Spicules equal, with double points directed posteriorly. An 

 accessory piece present. Eggs contain embryos when 

 deposited.

13. Haemonchiis Cobb, 1898. 

 Syn. Abomesi Simmonds, 1881 ( ? 1882). 



A small buccal cavity present, with a slender tooth or 

 lancet originating from the dorsal part of its base. A pair 

 of well-developed, spine-like cervical papillae present. Bursa 

 with large lateral lobes and a small, very asymmetrical dorsal 

 lobe attached to one of the lateral lobes near its base. Ventral 

 rays separate distally. Externo-dorsal rays very long and 

 slender. Main trinik of dorsal ray originates with the left 

 externo-dorsal ray in the left lateral lobe of the bursa, and 

 is bifurcate distally. Prebursal papillae present. Spicules 

 relatively short, barbed at their tips. An accessory piece 

 present. Vulva covered by a cuticular flap. Eggs segmenting 

 when deposited.
