BIBLIOGRAPHY OF PALAOZOIG CRUSTACEA 109 
The Agnostus described as 4. Schmidti has an unusual association, if occurring in 
strata with Microdiscus. ‘The Agnostus, however, is flatter than the typical species of 
the Paradoxides beds, and Dr. Matthew says it may be an earlier form.

On Parabolina spinulosa Wahlenb. as figured by Linné, Svenska Vet. Akad. Handl., 
vol. 20, 1759, showing one pair of antennae at their true place. 
Linné says: “Fig. 1 is one of the clearest specimens I ever saw among so many 
thousand. Most remarkable in this specimen are the antennae in front, which I never 
saw in any other example, and which clearly proves the fossil to belong to the insects.”

The author does not conform Beecher’s suggestion that Linné’s figure may be inter- 
preted as the thickened border between the facial sutures, but considers them as true 
antennae,

The author describes as new Triarthrus Becki var. macastyensis. 
This variety is like 7. Becki except the facial sutures are slightly more sinuous, and 
in front they diverge from the axis instead of converging as in 7. Beckii. 
Triarthrus jemtlandicus Lindstrém has a similar facial suture, though otherwise dif- 
ferent,
