The teoth ore in sockets placed obliquely, with conical crowns 

 compressed to sharp lateral niarpjins, and curved inward. The 

 proportions of the vertebral column are those of I'Ahhlnn, thouf^li 

 the transverse processes are lonj^er, as in Pai-eidsauruis. The ribs 

 are like those of a Mount renie, tho\i<;h the sacral ribs arc longer. 

 The shouldiT-j^irdle resembles that of J'i'ocolojihoii, and differs from 

 typical Anumodonts in the oonstitncnt bones bein<^ unanchylo.sed, 

 and in the j)recoracoid having a large anterior extension in advance 

 of the scapub.i. The sternum appears to have been unossifit'd, as in 

 Crucodilia. The humerus is widely exjtaiidod at both extremities 

 and twisted, but does not show the peculiar lateral curvature seen 

 in Monotremes. The ulna gives no evidence of an olecranon- 

 proccss; it is larger than the radius, and appears to articulate witli 

 the humerus. The pelvic bones are without acetabular or obturator- 

 perforations, are not anchyloscd together, and the ilium is not 

 expanded transversely. The hind-limb is no larger than the fore- 

 limb. The femur is more slender tlian the similar bone in Khidtui. 

 The fibula is prolonged proximally beyond the stout tibia, round 

 which it may rotate. The proximal row of the tarsus is one large 

 bone, formed of the blended astragalus and os calcis. 



In conclusion, the Author argues that the points of structure are 

 so few in which Monotreme mammals make a closer ajjproximation 

 to the higher mammals than is seen in this fossil and other Anomo- 

 dontia, that the Monotreme resemblances to fossil reptiles become 

 increased in importance. He believes that a group Theropsida 

 might be made to include Monotremata and Anomodontia, the 

 principal differences (other than those of the skull) being that 

 Monotremes preserve the marsupial bones and the atlas vertebra. 

 Ornithor/tynchiis shows pre-frontal and post-frontal bones, and has 

 the malar arch formed as in Anomodonts and some other reptiles.

The Dates of Esper's ' Schmetterlinge' By C. Da vies Shekboun, 

 F.Z.S. &c., and B. B. Woodward, F.L.S. &c. 



Thk following incomplete notes (pp. 138-140) on the dates of 

 E. J. C. Jasper's * I)ie europiiischen Schmetterlinge in Abbildungen ' 

 &c., collected over several years, may be useful to students until further 

 information be forthcoming. We have to thank Mr. L. B. Prout for 

 some valuable memoranda, the references "A. V.'' ( =Allgeraeiue3 

 Verzeichniss derer Bucher, &c. : Leipzig, Wcidmann) coming from his 

 manuscripts. " G. A." signifies " (iuttingisclie gelehrte Anzeigen." 

 The dates in 8(|uare brackets are doubtful and are those used by 

 Mr. Sherborn in his ' Index Animalium.' 



The dates of Esper's ' Die auslandischen (ausscreurop.) Schmet- 

 terlinge ' have been published by I'rof. Aurivillius in K. Vet.-Ak. 

 Handl. xix. (5) 1882, p. 182. VV'e think the date of the last three 

 parts (14-10, pp. 205-254) will bo found to bo 17'J8. The 1801 

 titlepage belongs to the so-caUed second edition.
