and Catulli, I cannot accept such specific names as Doriai, 

 Retziusi, Catulloi, but consider that they should be corrected 

 to Doriee, Retzii, Catulli. Another rule given by Linnaeus (and 

 Pabricius), which would seem to be forgotten by some modern 

 authors, is this : " Nomina generica, quam diu synouyma digna in 

 promptu sunt, nova non fingenda": I have therefore restored a 

 few such old generic names when they have been discarded for 

 newer ones. When an old genus has been divided into two or 

 more genera, I have retained the old generic name for the species 

 for which the author who first made the division determined that it 

 should be preserved *. If a species is described under two or more 

 different names in the same book or brochure, so that these names 

 have been published at exactly the same time, I do not think that 

 the law of priority compels us to consider the name that is first 

 printed as that which is, in all cases, preferable to the others (for 

 instance, Araneus sericatus, Clerck, instead of A. sclopetarius, id.); still 

 less can the species first described or mentioned by an author under 

 a generic name be said to have been considered by him as the type 

 of the genus, unless he expressly states that such was the case. 



In a previous publication " [Viaggio di L. Pea, etc. ii.] Primo 

 Saggio sui Ragni Birmani," 1887, I have cited the works, till then 

 published, in which Spiders from Burma are treated of; I have 

 shown that the number of known Burmese Spiders, which at that 

 period was only 33, had through Sig. Fea's beautiful collections, and 

 the addition of some other species mentioned in my above-named 

 work, risen to 157 1. Since that time only the following works 

 have been added to the list, and the number of known Burmese 

 species has been increased from 157 to 175 : —

J" Not 163 ; for of the 163 species catalogued by me in the above-mentioned 

 work, pp. 8-11, 6 must be excluded as being only the other sex (Homalattus 

 anafis), or, probably, varieties of other species (Argyroepeira bigibba, Herennia 

 mollis, Sa rotes vemutus, 8, caUipygiu, and Diapontia mmoms).
