BUDDELUND, I.SOPODA. 11 



I liud not al Ihal tiiiie seen any AfmadiUidiam witli the laininate appendages 

 lo the anterior Iruncal-legs, wliich form a niarsupium, noitlier liad I met any voung with 

 only six truncal seginents, and tlii.s was one oC tlie reasons why l placed this large 

 genus, cerlaiiily willi some doiibt, nearest to AruidHillo. Sincc I have found this 

 niarsupium on several species of ArmadillidUim, and have lor this reason and also on 

 account of the formation of tho mouth-parts later, "l p. 37, referred this genus to the 

 ÖHiscoided. 



With the exception of the species of the genus Arnntdillidium, I have not, how- 

 ever, found this marsupium on anv of the species of the genera referred hy me lo tlie 

 AriiK(dilloide<i. It niay lie added, however, Ihat a negative jiroof is no delinite proof, 

 and as 1 Jiave n(jt iiad fully developed female specimens of several species of other 

 genera for examination, neither I am able to prove tliat a marsupium is found there. 



As this cliarac'ter is found on the inajority of tlie iMarine-Isopods that have been 

 cxamined, and which appcai's lo be of vcry great importanre, it will he of importance 

 (o have dehnilivilv >hown, whether Ihe biological conditions, that have apparently shown 

 themselves with Ihe well developed abilily of conglobation, has acted as a hinderance in 

 the developmenl of the marsu|tium. 



Two genera which I have previously referred with some doubt to the subfamily 

 Onisdnae, PseudarniitdiUo Sai:ssukh:' and Aranthoiiisrus Kixaiian-, I now refer lo the 

 .subfamily Splicrillomnae. Of the PstiidarDtadil/o 1 have had opportunily of examining 

 specimens in the Berlin Museum; Acaidliom'srus I only know froin description and 

 figures of II. l!i( iiAUDSON, bul cerlain [loiiils here give me Ihe Impression, that it would 

 be corrcct to place it among lh(> Sjihi rlUoniuac. It is also certain Ihat Aii((pJiil(>scia^ 

 found by KACOvrrzA in a cave on the island JMalorca should be placed in the same sub- 

 family.
