The species of Ptgssiglottis described by Hallier hi. in Nov. Act. 

 Nat. Cur. Ixx. have with one exception been placed by Dr. Stapf, no 

 doubt properly, in Hallieracantlia (Journ. Linn. Soc, Bot. xxxviii. 

 6), to which must also be transferred three Bornean species, as below. 

 A few other transferences are included in the following list : —

MSS. 

 As he failed to find spurred anthers when examining the flowers 

 of these two species, Mr. Ridley suggests that the spurs may have 

 been bitten off by caterpillars, which he says occurs frequently. Is 

 it possible that the spur, at least sometimes, may in this wa}^ assist 

 in the pollination of the flowers ?
