The genus Andrya was proposed by Eailliet in the following words: 

 11 n'est pas doiiteux, bien que leiir ("tudc auatomique soit encore pen avaucce, que 

 les auoploceplialines des Ivongeurs, pourvus de jiores geuitanx alternes, doivent ctre 

 8Ci>arcs gon(?riquement de ceux des fiquides, qui out les pores genitaux uuilateraux. 

 Nous en faisous done le geure Andrya, d'aprt-s le Tamia rhopalocepltala Eielim, et en 

 rbonneur de Nicolas Andry, le savant medeciu du XVIP sit'cle, qui a contribuc I'uu 

 des premiers a (■lucider I'histoire des Teniad(?8. 



Besides tlie type-species, Eailliet placed, here Tcvnia rhopaliocephala, 

 Riehm {= Anoplocepliala cunicidi, II. Blanchard), and T. loimerosa, 

 Moniez. The latter si)ecies I return to the genus Anoplocepliala (p. 151). 

 In my preliminary note in 1895 I placed an American form {Andri/a 

 americana) in Eailliet's genus, but since examining Meyner's specimens 

 of Bertia mucronata I am inclined to transfer A. ameT'icana to the genus 

 Bertiiij see p. 105. Eegarding tlie validity of the genus Andrya, see p. 

 164. Of Eiehm's original material I have obtained the following speci- 

 mens: 



Cotypes of Eiehm's Tmnia rliopalocephala and Tcenia rliopaliocephala. 



All of these specimens were evidently originally determined by 

 Eiehni, who, however, trusted too much to the external form of the 

 segments, for a careful comparison of the worms with Eiehm's figures 

 and description shows that some of the specimens were misdetermiued. 



Eiehm states that his T. rhopalocephala was found only in Lepus 

 timidus, while T. rhopaliocephala {^Andrya cunicidi) was contined to 

 Lepus cuniculus. Whether the discrepancies between his labels and 

 this statement are due to an error in host determination or an erroj' in 

 writing the labels of the si^ecimens is a point which, of course, can not 

 now be settled. For the present I adopt his statements and assume an 

 error in the labels. If both host determination and labels are correct, 

 then Andrya cunicuU must also occur in Lepus timidus. This point 

 must be settled by new collection of material. 



None of the specimens are in very good condition, on which account 

 I am unable to enter into a detailed study of the organs. My observa- 

 tions, however, lead me to accept both species as well founded, and my 

 results agree in general with those obtained by Eiehm.
