IGO Misctllaneous, 



discovering and preserving the specimens on which the description 

 of the species was based. The details as to discovery and preserva- 

 tion, as given in my paper, reqxiire modification in this sense; and I 

 hope that future students will give Mr. Whitelegge the great credit 

 due to him, not only for bringing this very fine species to the know- 

 ledge of the scientific world, but for the great skill shown in the 

 preparation of the specimens which came under my notice.

On Glyphastrsea sexradiata, Lonsdale, sp. By P. Martin 

 Duncan, M.B. (Lond.), F.R.S., &c. 



In a communication to the Geological Society (Quart. Journ. Geol. 

 Soc. vol. sliii. Feb. 1887, p. 24) I described Glyphastrtut, Forhesi, 

 Ed. & Haime, sp., and stated that its alliance with Columnaria 

 sexradiata, Lonsd. (Quart. Journ. Geol. Soc. vol. i. 1845, p. 497), 

 was very close, and I gave the form the name Gh/phastrcea sexra- 

 diata, Lonsd., sp. At the time a very careful search was made for 

 the specimen described and figured by Lonsdale, but it could not be 

 found, although all the other types of Lonsdale's N.-American ter- 

 tiary species which were given to me by Sir C. Lyell were still in 

 my possession. After the publication of the paper a coral was 

 found by the Curator of King's College Museum ; it was one of a 

 number of fossils given by me to the College about twelve years since. 

 This coral had upon it in Lonsdale's handwriting, with which I am 

 very familiar, " Columnastrcea sexradiata." On examining this coral, 

 which is in the museum of the College in which I am Profes^or of 

 Geology, I find that the distinctions between it and a specimen of 

 GlypJiastrcea Forhesi, Ed. & H., sp., are not specific, but are due to 

 growth. This last-named species was later in time of description 

 than Lonsdale's, and therefore Ghjphastrcea sexradiata, Lonsdale, sp., 

 is the correct name for Columnaria sexradiata, Lonsd., and Gh/phas- 

 tra'a Forhesi, Ed. & Haime, sp. I am glad to be able to do this 

 justice to the late Mr. Lonsdale. Since I examined the coral, last 

 March, it has been cut without my knowledge or sanction.

On the first Changes in the Fecundated Ovum o/Lepas. 

 By Prof. M. NrrssBAUM. 



During the author's residence on the coast of California he was 

 able to obtain an abundance of material. All the ova in the same 

 animal are at the same stage of development, but the animals are 

 very abundant and the breeding-season lasts for several months, so 

 that by continued preparation the diflerent stages may be obtained 

 in different animals. 



The author's description commences with the stage at which the 

 copulation of the male and female cells is eftected, and the masses 

 of ova enclosed in a thin homogeneous sac protrude from the orifices 

 of the oviducts into the space within the shell on each side of the 

 head. The ova are small and numerous, ovate, with a blunt and
