admirably selected and well executed, except 

 for their tendency toward schematization. The 

 original figures are not numerous and are chiefly 

 diagrams. 



In conclusion, it may be said that any stu- 

 dent who, with the aid of practical laboratory 

 work, masters Hertwig's book will have mas- 

 tered the general subject of human embryology 

 from the comparative morphological standpoint, 

 and will be qualified to pursue more advanced 

 study, but he must remain ready to modify 

 many of his general theories and to fill out a 

 number of important gaps in his knowledge. 

 His chief gain will be insight into the very 

 spirit of morphology, through the guidance of 

 one of the very ablest of morphologists.

A Handbook of the British Macro-Lepidoptera. 

 By Beeteam Geo. Rye. With hand-col- 

 ored illustrations by Maud Hoeman- 

 FiSHEE. London, Ward & Foxlow. Parts 

 1-4, Jan.-Oct., 1895. 



The four parts issued give a fair idea of the 

 scope and execution of this addition to the al- 

 ready large number of works relating to the 

 butterflies and moths of Great Britain. Each 

 part contains eight pages and two plates. 



In the introduction the changes that take 

 place during metamorphosis and the principal 

 characters used in classification are briefly de- 

 scribed. Eight families of Rhopalocera are 

 recognized, namely, Papilionidse, Pieridse, Nym- 

 phalidae, Apaturidse, Satyridse, Lycsenidffi, 

 Erycinidae and Hesperidae. A table separa- 

 ting these is given, and the genera and species 

 can be readily distinguished by means of simi- 

 lar tables. The species are fairly well de- 

 scribed, and the notes on the early stages, 

 haunts, times of appearance, and abundance 

 are clear and concise. 



The plates are excellent, and the distinctive 

 value of Mr. Rye's work consists in the de- 

 scription and illustration of the varieties and 

 local races, apart from the consideration of the 

 species, of the Macro-Lepidoptera of Great 

 Britain. Beginning with 1896 the parts will 

 be issued bi-monthly, instead of quarterly. The 

 price per part is 2s. 6d.

Mollusca and Crustacea of the Miocene Formations 

 of New Jersey. By R. P. Whitfield. Mon- 

 ograph U. S. Geol. Survey. Vol. XXIV. 1894. 

 This latest contribution of Professor Whit- 

 field to the paleontology of New Jersey is most 

 opportune, since the detailed mapping of the 

 coastal plain formations of the State has re- 

 cently shown an extensive development of 

 Miocene strata. The character of the deposits 

 is such, however, that determinable fossils have 

 only been detected at a very few points, the 

 great majority coming from the marl beds in 

 the vicinity of Shiloh and Jericho and from the 

 deep well-borings at Atlantic City. These 

 forms Prof. Whitfield has evidently studied with 

 great care and has presented in a most accepta- 

 ble manner. 



Prior to the publication of this report by Prof, 

 Whitfield, little systematic work had been done 

 upon the fossils of the Miocene of New Jersey. 

 Meek's list, published in the ' Smithsonian 

 Miscellaneous Collections ' in 1864, contains 

 reference to only seventeen species. Prof. 

 Heilprin in his ' Tertiary Geology of the eastern 

 and southern United States, ' published in 1884, 

 gives twenty-seven species, seventeen of which 

 he regards as peculiar to the State. Later, 

 from time to time, the same author added to 

 this list, until in 1887, in an article on ' The 

 Miocene Mollusca of the State of New Jersey,' 

 he enumerates eighty-two species, describing 

 three new species and one variety. 



In his monograph Prof. Whitfield recognizes 

 one hundred and four species, but states that 

 there is no doubt that many more species might 

 be obtained were the beds more thoroughly ex- 

 amined and other localities explored. Of the 

 species described thirty-six are regarded as pe- 

 culiar to New Jersey. 



Besides the molluscan remains enumerated, 

 Mr. Anthony Woodward gives a list of twelve 

 species of foraminifera found in the marls at 

 Shiloh and two at Jericho. 



Prof Whitfield, from a study of the fossils, 

 would correlate the deposits with the Miocene 

 of the States to the south, which is fully sub- 

 stantiated upon physical grounds as well. The 

 writer of this review has traced the strata across 

 Delaware into Maryland so that there can be 

 no doubt but that the New Jersey Miocene is
