*AMCEBOT.ffiNIA SPHENOIDES " (Railliet, 1892) Cohn, 1899.

Genus LIGA Weinland, 18B7. 



Fuhrmannia Parona, 1901 (type, F. brasiliensis Parona). 



Generic diagnosis. — Dipylidiinse : Rostellum armed with a double 

 crown of hooks with long dorsal and short ventral root. Strobila 

 with 12 to 16 segments. Genital pores regularly alternate; located 



a Frolich (1802a, pp. 86-87, pi. 2, figs. 23-25) described a species under the name 

 of Tsenia stentorea Irovn Tringa hypoleucos, which Rudolphi (1819a, p. 498) considers 

 identical with Taenia variabilis. The name stentorea should replace variabilis if it 

 can be proved that Frolich's paper appeared prior to Rudolphi's paper of 1802, other- 

 wise the species should continue to be known as variabilis. 



bSynonomy — Tasnia cuneata Linstow, 1872, not Batsch, 1786; Taenia sphenoides 

 Railliet, 1892; Dicranotxnia cuneata (Linstow, 1872) Railliet, 1893; Dicranotxnia 

 sphenoides (Railliet, 1892) Railliet, 1896; Amoibotsenia sphenoides (Railliet, 1892) 

 Cohn, 1899; Amcebotsenia cuneata (Linstow, 1872) Cohn, 1901. 



This species has been fully described by Cohn (1901b) under the erroneous name 

 Amoebotsenia cuneata. Tsenia cuneata Linstow, 1872, is a homonym of Tsenia cuneata 

 Batsch, 1786; hence, under the International Code of Zoological Nomenclature, the 

 name cuneata can not be used for the species described by Linstow in any generic 

 combination whatsoever. 



Amoebotsenia sphenoides has been found in this country in Maryland and the Dis- 

 trict of Columbia (Bureau of Animal Industry Helminthological Collection Nos. 14521, 

 14713, 14746).
