KEMATODE CJENUS PHYSALOPTERA. 1103 



(91) Physalopi;era mucronata Diesing, 1851. 



Host : Alligator mississi2ypiensis. Georgia, 

 This parasite has been found by Molin to be an Ascarid, and 

 von Drasche has identified it with Ascaris lanceolata MoL, 1860. 



(92) Physaloptera ovata v. Linstow, 1907. 



Length of male 13'8mm. ; length of female 16-8 mm. by 

 1*22 mm. thick. 



Mouth surrounded by 6 cones. (Esophagus of male l/4"4, of 

 female 1/3-5, tail of male l/i4th, of female l/53rd of body-length. 



Bursa oval, with 5 pairs of equidistant and lateral stalked 

 papillae, the 2nd being the longest ; 2 pairs are pre- anal. 

 Spicules equal 290 /x, long. 



The vulva divides the body into the ratio of 13:31. Eggs 

 narrow, 42 x 13 /x. 



Host: Astur melanoleucus. Yentriculus. Cameroon (Kamerun). 



The nature of the lips rules this species out of the genus 

 Physaloptera ; this is supported by the nature of the bursal 

 papillae and by the exti-emely narrow egg. 



The description is too incomplete to definitely say to which 

 genus it should be transferred, but it appears to have some 

 resemblance to the geuns^Cyrnea Seurat, 1914. 



(93) Physaloptera saginata Kud., 1819. 



Syn. Spiroplera saginata (Rud.), Duj., 1845. 



I examined examples of this species from Comes cajanus and 

 Cap7-imulgus guianensis while at Vienna, and am consequently 

 able to confirm Molin's (1860) view that this species is a Spiro- 

 ptera. 



(94) Physaloptera striata v. Linstow, 1883. 



Length of male 18 mm,, breadth •48 mm.; length of female 

 25 mm., breadth •66 mm. 



Two dorso-ventral lips, small and rectangular, having a wavy 

 anterior border and divided into three parts internally ; 4 small 

 interlabia. Tail of male spirally rolled, 1/37-5 of body-length ; 

 tail of female rounded, l/83rd of body-length. 



Caudal alse of male with longitudinal striations. Four pairs of 

 pre-anal stallied papillae ; 1 unpaired papilla in front of anus : 

 2 pairs post-anal and dividing tail roughly into thirds. 



Vulva divides body into ratio of 3 ; 2. Eggs 46 x 25 [x. 



Hosts : Tropido7iotus liydrus. Turkestan. 



Ciconia alba. Stomach. Turkestan. 



Seurat has obtained a Cyrnea from difierent species of Ciconia^ 

 which he identifies with Fh striata. This species is undoubtedly 

 not a Physaloptera, and from von Linstow's figure and description 

 of the lips I think Seurat is correct in transferring it to his 

 genus.
