112 MR. H. CHARLTON BASTIAN'S MONOGRAPH 



" Hab. In focibus aceti {Borellus, Miiller, &c.) ; in aceto communi cerevisise et vim, 

 in aqua cum forina, in aqua cocta, et in faicibus cerevisiai, Moscoviae ( Czernay) ; in aceto 

 e pomis parato, frequenter Philadelpbige (Leidi/)." 



" Nota 1. Larvas muscae cujusclam (Mosilli cellarii ?) in aceto obvias cum liac sjiecie 

 confundit Spallanzani (Microsc. Eeobacht. 176). 



" Nota 2. Probabiliter e Mosilli cellarii intestinis in acetum translata." — Diesing. 



If the drawings are accurate (Pop. Sc. E,ev. Jan. 1863) of the animal discovered, by 

 Mr. Jabez Hogg, about portions of the common truffle left for some days moistened with 

 vinegar, I am rather inclined to believe that this will jn-ove to be a distinct species, and 

 not the real A. aceti, since it differs in several respects, more especially as regards 

 the male spicules, from the animals examined by myself, concerning which there can be 

 little doubt, seeing that they swarm in a specimen of pure vinegar, kindly sent to me by 

 M. Davaine.

" Corps filiforme, assez 6pais, long de l'"'"-68 ; vingt fois environ aussi long que large, 

 amincie en arriere et termini par une pointe fine allongee ; vulve situee au tiers poste- 

 rieur ; oeufs grands (de 0"""'09) a coque membraneuse et contenant un embryon replitJ."

" Hah. In glutine fjirina? [Baker, Midler, &c.) ; in glutine tritici, secalis, tragacanthi, 

 etc., frequenter Philadelphia? [Leidy)." — iJiesing. 



In the paper before alluded to, Mr. Hogg seems to doubt the fact of any specific differ- 

 ence existing between this form and Aiiguillula aceti ; but, from the descriptions of 

 Dujardin, there appears to be a great fliscrepancy in the compax*ative dimensions of the 

 two. Thus, speaking of Anguillula aceti, he reports it as, " trente a quaraute-cinq fois 

 aussi long que large," and so making the body much narrower than in A. glutinis. M. Da- 

 vaine believes them to be distinct species, and says, in a letter lately received, " D'apres 

 quelques recherches que j'ai faites, il y a quelques annees, je pense que les vers de la 

 colle de pate viennent de la terre, oil elles vivent normalement dans les grains ou dans 

 les racines qui contiennent de la fecule." 



All my attempts to procure these animals in ordinary wheaten paste have been imsuc- 

 cessful, though I have taken every precaution to ensxire the purity of the flour.
