 some of tho specimens 1 have j^laced in II. prrvica.r m\i;lit bo i-e- 

 ferable to H. fuscocincrca. It wonld 1)0 liclpfal if those who haA'o 

 spoeimons of tho latter species wonld carefully re-examine the 

 point in question. The only point in which the two species seem 

 to differ consists in the shape of the buttons, and this can ])robably 

 be bridged over. 



Bedford's statement that II. nrgu^ .Jaeoeu is a close ally of 

 the present species, I can not sn]»port, as the two species are 

 very clearly distinguishable both in calcareous deposits and in 

 coloration. For details see the description of TI. arr/ii.^ in the 

 present memoir.
