S.flava differs from S. badia of Erichson (on which the genus 

 was based), according to the specimen in Mr. Baly's cabinet : 

 the species before us is smaller in size, the form is more com- 

 pressed and flat, and the colour of the legs is different.

A. latus, satis depressus, subtilissime punctatus, rufus : caput ad 

 antennarum basin transverse foveolatum, impunctatum : antenna 

 graeiles, art. 1—3 flavis, 4-9 nigris, 10° et 11° testaceis : thorax 

 transversus, ad basin arcuatus, frons etiam sinuata (apud medium 

 rotundato-subporrecta) ; latera late marginata, et versus apicem 

 angulata ; thorax punctatus, nitidus : scutellum triangulare, Iseve : 

 elytra lata, rotundata, subtiliter punctata : corpus subtus nigrum 

 vel nigro-piceum, abdomine rufo : pedes nigri.

Under the head of Argopus will be found ranged in many of 

 our cabinets species from India, the East, Madagascar, and the 

 Cape which clearly require the construction of two or three 

 special genera for their reception. The species before us differs 

 from the true Argopus, both in the form of its palpi, its some- 

 what different appendiculations of the claw, and the peculiar 

 lateral angles of the thorax. I prefer, however, to place it here, 

 at all events provisionally, than to seek to establish a new genus 

 in a difficult and numerous group, on the basis of a single 

 species.

The earliest remains of Pterodactyles yet figured are from the 

 Lias. Professors Buekland, Owen, and Huxley have described 

 the Dhnorphodon. I therefore approach the subject with diffi- 

 dence. But my task now is not to describe these remains, but 

 to examine the nature of the work bestowed upon them. 



Prof. Buekland' s is the only description of the specimen 

 figured in pi. 27, Geol. Trans, ser. 2. vol. iii. ; and the remarks

 March 7 and May 2 and 16, 1864.
