is about two-thirds of the original. The specimen is in the mineralog- 

 ical museum of the University of Copenhagen, but according to a 

 statement of Prof. N. V. Ussing it is said to be in a poor state 

 of preservation and seems to be gradually approaching destruc- 

 tion. * * * 



During his journey in Skane, Linne noticed in the aluminous 

 shales at Andrarum the Insectorum vestigia, already described from 

 that place by Bromell, in which the former recognized animals of the 

 same grouj? he had previously observed in Oland and Westrogothia, 

 " although there as large as a fist, but here in Andrarum not larger 

 than flies." The trilobite in question, named in the Systema Natures 

 '"'' Entomolithus paradoxus {3 Canthandium,^'' is the Olenus truncatus. 



On the other hand, he found it difficult to determine the " Vermicu- 

 lorum vaginipennium imagines," also occurring in this place and cited 

 by Bromell, which, however, he later recognized as belonging to the 

 same animal group, and introduced in the Systema Naturae as 

 '■^Entoiii: farad, y Pisifoimis,^'' or what we now call the ^''Agnostus 

 fisiforinis.^'' 



In the Vetenskapsakademiens Handlingar, 1759, Linne contrib- 

 uted a special paper, accompanied with illustrations, on the fossil 

 Entomolithus -paradoxus, in w^hich he included all trilobites. * * * 

 Two of these need not arrest our attention; they are pygidia of 

 Galymrfbene pninctata and C . hlumenbachii (according to Wahlenberg 

 and Dalman), while the third is the most interesting. Linne says of 

 it that it " is one of the most perfect specimens I have been able to 

 find among many thousand fragments," and, further, after having 

 described the thoracic shield and the somatic segments, the lateral 

 j)arts of which [pleurae] " are not feet, but an outgrowth of the 

 shields proper," he says : 



The most peculiar feature of this specimen is. first of all, the autemife. \A'hich 

 we have never seen in any other, and which most plainly demonstrate that this 

 fossil must belong to the insect genus ( to which at that time the Crustacea were 

 referred), or, to be more exact, a genus intermediate between Cancros, Monocu- 

 los, and Oniscos. * * * 



"VVliile it is true that the specimen described by Linne, which is 

 usually considered to be the Paraboli^ia spimdosa, and at all events is 

 an olenid, has been mentioned since that time by several of those who 

 have investigated the trilobites, it seems that there has been a gen- 

 erally indifferent or skeptical attitude concerning the antennae pointed 

 out by Linne. Wlien tow^ard the end of the last century it was shown 

 by American scientists that the trilobites actually possessed antennae, 

 S. L. Tornquist called attention to Linne's observation, and on this 

 subject there arose a discussion between the former and C. E. Beecher, 

 the American geologist, who pretended not to see a trace of antennae
