they are often all well-marked and emerge simultaneously in 

 countries where ])ractically no wet-season exists ; but, on the 

 other hand, in countries where the weather is more or less 

 moist throughout the year the dry forms are either wholly 

 absent or are extremely rare (probably only existing as 

 reversional sports). 



T. ampJexa group. 



In this group the outer borders are quite regular — that is 

 to say, not widening towards the apex of the primaries, as in 

 the extreme dry phases of the T. hecabe group.

Our males are all of the wet-season type, and our single

X. — A Bevision of the Linnean Type Specimens of Scorpions 

 and Pedipalps in the Zoological Museum of the Royal 

 University at Upsala. By Dr. EiNAR LoNNBERG. 



From the time of Linnaeus three Scorj)ions and two Pedipalps 

 have been preserved in the Zoological Museum at U])sala. They 

 were all five mounted on pins by Tliunbcrg, and are provided 

 with his handwritten labels, which not only give the specific 

 name, but also define the " collection " to which they belonged. 

 It is consequently easy to find the names in the catalogues 

 written by Thunberg. The first scorpion among these is 

 labelled " q/e?', Mus. Ad. Fr.," which means that it belonged 

 to the collection which the then Crown Prince Adolj)h Frcdrik 

 presented to the University in 1745. This collection was 

 afterwards described by Linnajus in the ' Dissertatio Aca- 

 demica/ which was defended by L. Balk, 81st May, 1746, 

 in a work entitled ' Museum Adol[)ho-Fridericianum ' *, 

 and reprinted in ' Amcjenitates Acadenuca},' t. i. no. xi. 

 pp. 277-326, under the title ' Museum Principis.' Ilere 

 we also find the scorpion as No. 61 " Scorpio pectiimra 

 denticulis Xlll." The specimen in question is thus a type, 

 or one of the types, of the " Scorj/io afer^^^ which in ISyst.
