Haplosplanchnidae Poche, 1926 



Haplosplanchnus acutus (Linton, 1910) 



Hosts : Tylosurus fodiator Jordan and Gilbert 



Kyphosiis elegans (Peters) ? 

 Location: Intestine 



Localities: Port Utria, Colombia 



Charles Island, Galapagos 



Number : 4 in Tylosuiois ; one in Kyphosus 



This species has been recorded hitherto (by Linton, 1910 and Manter, 

 1937a) from Tylosurus acus, T. marinus, and T. raphidoma at Tortu- 

 gas, Florida, and at Bermuda. 



Haplosplanchnus pomacentri Manter, 1937 



Host: Pomacentrus rectifraenum Gill 

 Location: Intestine 

 Locality: Charles Island, Galapagos 

 Number: 2 



This species is recorded by Manter, 1937a from Pomacentrus leuco- 

 stictus and P. xanthurus at Tortugas, Florida. Its occurrence in a related 

 yet shallow-water reef fish in the Galapagos is of some interest. 



Monorchidae Odhner, 1911

 (Plate 44, figs. 87-89) 



Host: Anisotremus interruptus (Gill) 



Location: Intestine 



Locality: James Island, Galapagos 



Number: 2 specimens in one of 3 hosts examined 



The following specific diagnosis is based on 2 specimens from the 

 above locality and one specimen from Anisotremus virginicus (Linn.) 

 from Tortugas, Florida. Specimens from both regions are figured (figs. 

 87 and 89), and differences are discussed below.
