1890.] Ernst Hartert— On Poritia harterti, Duherty. 205 



a lepidopterist, I may perhaps be allowed to make a few remarks on that 

 interesting and valuable paper. 



1. On p, 123 it is stated that " the specimens described below are 

 in Mr. Neumoegen's collection unless the contrary is stated ;" as some 

 mistake might arise oat of this, 1 may say that all the specimens caught 

 by me during that trip to Assam are in Dr. Staudinger's collection at 

 Dresden. Amongst them are the only fine untorn specimens of Aemone 

 amathusia, Hew. (A pealii, W,-M.), two fine males of Apatuua {Potamis) 

 ulujpi, Doherty, Poritia harterti, Doherty, and many others. 



2. With regard to Poritia* harterti, the allied species Poritia 

 phalena, Hew. has only been taken by Mr. A. R. Wallace near Singapore 

 and has never been procured since, so that Doherty was certainly justified 

 in considering that my specimen taken far away north in the Patkoi 

 hills in Assam was a different species or at any rate a geographical 

 race. Unfortunately, Mr. Doherty had no specimen of Poritia phalena 

 with which to compare the Assam Poritia but only the very poor figure 

 in Distant's Hhopalocera Malayana (PI. XXII, Fig. 8) and perhaps that 

 in the Illustrations of Diurnal Lepidoptera (Lycaenidce, PI. LXXXIX) 

 with the accompanying descriptions. 



I, however, was lucky enough some time after to secure in the Baltak 

 hills in ISTorth East Sumatra, almost in the verandah of the house of my 

 friend Dr. Martin, of Munich, another specimen of Poritia ; a comparison 

 of this Sumatran, specimen with the Assamese one showed that the two 

 were undoubtedly identical ; moreover, I found that my Sumatran specimen 

 agreed entirely v?ith the description of Poritia phalena, Hew. ; the com- 

 pai-ison was made by me with Dr. Staudinger, who is also of my opinion. 



It therefore seems to me that the species named by Doherty after 

 me Poritia harterti must be relegated to the large and increasing class of 

 synonyms. 



3. Coins of Sallakshana Pdia Deva, Madana Pdla Deva, and Pri- 

 thivi Deva, by Vincent A Smith, B. S. C. 



The late Mr. Edward Thomas was a numismatist of such skill and 

 experience that mistakes in his work cannot often be detected, but I 

 observed long ago errors in the attribution of the coins of the princes 

 named in the heading of this note, and should have pointed out the 

 mistakes earlier, only that I supposed them to be so obvious as not to be 

 likely to mislead any one accustomed to numismatic researches. 



Now, however, I perceive that so good a scholar as Dr. Hoernle has 



* This butterfly is placed by Doherty in the genus Messaga ; for my part I see 

 no reason for retaining a genus distinguished by such slight differences.
