Paradoxides cf. Mclcsii Salter & sjogreni Limiarsson, and Paradoxides

The type-specimens are numbered [1828, 1832]. * 

 Orasudiem : PI. II, figs. 1, 3, and 4. 

 Dimensions in millimetres: — 



Length 24 



Width across anterior angles 28 



Width across eyedobes 29

LeDgth of chord of eyedobe 10 



Length of do. do. and ocular ridge together... 12£ 



General form. — Quadrate, with deep notches in front of the 

 •eye-lobes. 



General convexity. 2 — About 1 : 4. 



Glabella. — Moderately convex; circularly rounded in front; 

 widest at about a third of its own length from the front ; 

 narrowing to about two-thirds of this width at the occipital ring ; 

 with four pairs of furrows, of which the anterior is situated at the 

 widest part and is short and rather indefinite, the second is some- 

 what longer (but also weak), the third is strong at the sides, but is 

 rarely traceable across the axial line : all three pairs are disconnected 

 from the axial furrow, while the fourth pair connects with it, is 

 strong at the sides, and is continued across the axial line as an 

 ill-defined shallow hollow. 



Occipital furrow. — Straight and well-marked, except in the 

 middle third, where it is somewhat ill-defined. 



Occipital ring. — Wider in the middle than at the sides, so 

 that the border projects strongly backwards. 



Axial furrow. — Very little impressed. 



Pixed cheeks. — Convex; highest near the glabella; marked 

 diagonally, from the end of the occipital furrow towards the middle 

 of the eye-lobe, by a change of curvature. This diagonal mark is 

 •seen in two specimens, but may be due to accidental damage before 

 fossilization. 



Eye-lobe and ocular ridge. — Long and wide; extending 

 from the postero-lateral furrow to the glabella ; gently convex ; 

 separated from the fixed cheek by a distinct but lightly-impressed 

 line. 



Postero-lateral border. — Purrow narrow, straight, and but 

 little impressed ; marginal fold wide and gently convex. 



Pront. — A gently convex fold curves round the front of the 

 glabella, and is separated from it by a shallow groove ; both become 

 gradually less marked as they are followed towards the facial suture, 



1 The numbers in square brackets are those attached to the specimens in 

 my collection for the Excavations Committee of the British Association. 



2 That is, the ratio of the maximum height of the glabella to the maximum 

 width of the shield.
