fences due to the fact that lie was dealing with species distinct 

 from ours, Prof. "Whkki.er'.s account is cjuite in accord with that 

 of Dr. SoRKNSEX and myself. 



In 'Das Tierreich' 12. Lieferung (Febr. igoi) Prof. K. 

 Kr.'^epklin deals with the order Palpigradi, but his account 

 being based only on the literature already enumerated a special 

 mention is scarcely necessary. 



The number of "/ool. Anzeiger' published Se])t. 16. 1901 

 contains an essay by stud. rer. nat. Carl Borner: Zur äusseren 

 Morphologie von Kocncnia mirabilis Grassi (B. XXIV., No. 652. 

 p. 537 — 56; with twelve figures in tlie text). He refers to our 

 paper as follows: »Alle wesentlichen Puncte, möchte ich sagen, 

 finden sich hier zum ersten Mal richtig beschrieben. Nichtsde- 

 stoweniger bedarf auch diese Beschreibung einiger 'Verbesserungen 

 und Zusätze, die in der phylogenetisch-systematischen Auffassung 

 von Kocjunia nichts ändern, für eine specielle Systematik, zum 

 Vergleich mit anderen, wie ich glauben möchte noch in grosser 

 Zahl zu entdeckenden Arten dieser Familie, jedoch von nicht 

 untergeordnetem Werthe sind-. F^or various reasons I think it 

 useful to examine more closely the contents of an essay with 

 such promising sentences. All points worth mentioning will be 

 dealt with, but their consecutive order is partially altered. 



Mr. Borner writes (p. 538) that we (H. and S.) »bilden 

 den Céphalothorax in etwas geciuollenem Zustande ab, etwa so 

 wie er nach der Behandlung mit Kalilauge etc. eintritt. Man 

 erkennt dies an der Insertion des vorderen Doppelsinneshaares 

 und an der starken Wölbung der hinteren Partie des dorsalen 

 Carapax). But his description, his fig. i and especially fig. la 

 (both figures unfortunately diagrammatic) show that his specimens 

 were contracted by the action of strong spirit or perhaps other 

 fluids: when collecting the animals he evidently preserved-them 

 for the purpose of anatomical study by section-cutting. (He kindly 

 lent me a specimen with the fiagellum complete along with some 

 specimens of Pauropiis and Scolopcndrclla: the Kocncnia (stai- 

 ned and mounted in balsam) is exceedingly contracted, and all 

 the other animals are stift", hard and considerably or much con- 

 tracted). ^\■hen collecting such animals as Kocnciiia and small 

 Myriopods I always j^ut them into spirit of only 60 — 63 j'^ and
