 It might appear from the above synonymy that the name of the species should be 

 'puter;' but Eisen himself pointed out that his Lumbricus puter was not the same 

 species as Hofpmeistee's Lumbricus puter : both Vejdotsky and Kulagin (3, p. 94) 

 regard Lumbricus rubidus of Duges (1) as a synonym of the present species. 

 Vejdovsky remarks upon this question (24, p. 60), ' Unbegreiflicher Weise legt Hoff- 

 MEiSTEE Ent. rubidum als Synonym zu seinem Lumbricus olidus, was ich nur 

 aus dem Umstande erklare, dass er, wie er erwahnt, nur die in Weingeist konser- 

 vii'ten Savigny'schen giirtellosen Typen vergleichen konnte. AUein die schon von 

 DuGi;s gegebene Beschreibung von seinem Lumbricus rubidus zeugt, dass diese Art 

 mit Luynbricus puter, Hopfm. identisch ist. Duges sagt namlich, pag. 23 : " Du reste 

 il y a aussi de ba\idelettes (tubercula pubertatis, Eisen) sous le trenti^me, trent et 

 unifeme, et trent deuxifeme anneaux ... Ce qui le distingue surtout, ce sont les 

 rang^es de soies trfes dcart^es les unes des autres, quoique r^ellement g^min^es." ' 

 Vejdovsky, however, has overlooked another point in the description of the species, 

 and that is the position of the spermathecae, which open close to the dorsal median 

 line. This character is evidence of the speciae being really Lumbricus olidus of 

 HoFPMEiSTER ( = A.foetida), or perhaps A. veneta of Eosa, which was not, as a matter 

 of fact, described at the time when Vejdovsky wi"ote. Rosa certainly says nothing 

 about the spermathecae of AUolobophora boeckii ; neither does Eisen ; but Rosa places 

 it in his fourth group of Allol6bop}tora, which is characterized by the fact that these 

 organs open in line with the third seta. Vejdovsky finds but one pair, concerning 

 the exact position of the orifice of which he says nothing. The setae too of AUolo- 

 bophora boeckii, although they resemble those of Hofpmeister's species in being in 

 four rows, are really different in their arrangement ; and are, according to RoSA, 

 sufficient in themselves to identify the species. The lateral spaces are nearly equal, 

 but decrease slightly from below upwards. These spaces are so large that the 

 dorsal space is only twice the width of the superior lateral space ; the ventral space 

 is smaller than the dorsal and is only a little wider than the inferior lateral space.
