five pelvimyoiis ; the so-called "obturator intermis"; several svrinomva: 

 and the tendons of profundiplantar mya. The five pectorimya treated 

 are: — i, tensor patagii longus ; 2, tensor patagii brevis; 3, dermotensor 

 patagii ; 4, bicipital slip to the patagium ; and 5, expansor secundariorum.* 

 The five pelvimja discussed are the ambiens and those other four alreadv 

 handled with much effect by Garrod and others under their respective 

 symbols, A, B, X, Y.f If the author is correct in identifying the muscle 

 he called "obturator internus" with the myon of that name in hominisec- 

 tion, it is the obturiformis of Coues and Shute,J whose origin, whether 

 oval or triangular, is discussed in its possible bearing on classification. 

 The paper concludes with remarks well worthy of attention, on the 

 profundiplantar tendons. It is quite fully illustrated with thirteen figures, 

 in part original. — E. C. 



A New Ornithichnite.§ — Prof. F. H. Snow describes and figures a 

 fossil, apparently that of a true bird, found in August, 1885, i" Ellsworth 

 Co., Kansas, in an excavation 44 feet deep in the Dakota Sandstone, on 

 a geologic horizon about 200 feet below the upper level of the Dakota 

 rocks. "The impression appears to have been made by the left foot of 

 some bird with elevated hind toe just reaching the ground at its extrem- 

 ity, as in the modern Snipes and other Wading-birds, or in the family of 

 Sea Gulls and Terns." The fossil is a small one, only two inches in 

 total length. The object is not named, but Prof Snow compares it with 

 such a track as the foot of an Ickthy'ornis might have made." The discov- 

 ery of this avian footprint. . . .considerably lowers the geological horizon 

 of Kansas birds," which were not before known from strata below the 

 Niobrara group, or highest of the Cretaceous rocks, beneath which the 

 Dakota "rests unconformably upon the Permio-Carboniferous, with 

 apparently an entire exclusion of the Triassic and Jurassic formations."

Clark's 'Birds of Amherst.'|| — This annotated list of the birds occurring 

 about Amherst seems to have been written not as an exhaustive contribu- 

 tion to faunal literature, but rather for the enlightenment of the farmers 



*The progress of improvement in myological terminology makes it desirable to re- 

 name some of these mya. They may be called : i, longitensor patagii ; 2, brevifensor 

 patagii; 3, dermotensor patagii (of Shufeldt) ; 4, bicipitensor patagii; and 5, secund- 

 expansor. 



tA =femorocaudal; B = "accessory femorocaudal," which is now named accessi- 

 caudal; X = semitendinosus; Y = "accessory semitendinosus" which is now called 

 accessitendinosus.
