Systematics of the Pedipalpl. 159 



too, that Latreille carefully cites reniformis, Fabr., not reni- 

 formis, Linn, or Fall., as the " exemple " of Phri/nus. 



Thus with regard to the two species of Ambljpygi under 

 discussion the method of settling type-species by elimination 

 gives the following results : — 



1. reniformis, Linn. (=lunatm, Pall), comes out as the type of Taran- 



tula by Lamarck's elimiriatioti unler Phrynus of caudaius and 

 the species wrongly called reniformis by Fabricius, 



2. The latter comes out as the type of Phrynus by Latreille's removal 



of caudatua under Thelyphonus. 



The next author to take up the genera of the group was 

 C. Koch in 1850 (' Uebersicht,* &c. v. p. 81). He arranged 

 them as follows : — 



1. Phrynus, to include ceylonieiu, Koch ; lunatus, Pall. ; niyrttnanus, 



Koch ; mediiis, Ilerbst. 



2. Damon, nov., for van'eyatua, Perty ; reniformis, L^ as erroneously 



restricted by Pallas. 



3. Admktus, nov., for pumilio, Koch; pabnaUis, llavhst; fuscimanu!*, 



Koch ; maryinemaeulatua, Koch. 



Phrynus^ however, was already restricted by Latreille to 

 reniformis, Linn., as restricted by Fabricius. Hence Koch's 

 application of the name was inadmissible. For Damon and 

 Admetus any one of the species cited under them might come 

 out as the type. 



In 1879 (Arch. Naturg. p. 197) Karsch proposed the 

 following systematic arrangement : — 



1. Phrynichus, nov. Type reniformis, Linn. ( = lunatus, Pall.). 



2. Damon, Koch. Type medius, flerbst { = variegatus, Perty). 



3. Tarantula, Fabr. Type /jmhuVjo, Koch (=re>«/ci/v»w, Pallas, nee 



Linn.). 



4. Charon, nov. Type Grayi, Gerv. 



For the first name Phrynichus, reniformis, Linn. ( = Iunatiis, 

 Pall ) is cited as the type. But since this species is also the 

 type of Tarantula, Fabr., as already pointed out, Phrynichus 

 falls as a synonym of Tarantula. It will be observed that 

 Karsch rever.ses the action of Pallas and Fabricius, and 

 rightly makes the species exemplitied by the specimen in the 

 Mus. Ludov. Ulr. tlie type of reniformis. 



The second name Damon is restricted to variegatus, the 

 supposition that medius, Herbst, is identical with variegatus 

 being erroneous. 



The third name TARANTULA is assigned to a species 

 originally included in the genus as a synonym. But the 

 name wus already taken up for reniformis, Linn. : hence the
