thtM'e exists, so far as I have seen, no visible evidence of any sexual 

 form of I'eproduction. The development of the fruit is a purely veg- 

 etative jM'ocess analogous to that seen in many Ascomycetous fungi. 

 4. In all such lichens, as far as my observation goes, there exists at 

 no stage in the development of the fruit any differentiation of the 

 hyphae into an ascogenous system and an enveloping system distinct 

 from it. Both asci and paraphyses arise from one and the same 

 system of hyphae, and with respect to their origin exhibit the closest 

 mutual relationship, thus presenting a marked analogy to those 

 Ascomycetous fungi in which the fruit arises as the result of a purely 

 vegetative process of hyphal growth. 



Dr. Sturgis has found that sections made by hand are more satis- 

 factory than with the microtome. With those lichens having a 

 tough cortex the parafifine penetrates very slightly, if at all, while 

 the gelatinous species are likely to be much distorted during the 

 process of embedding. r, s. e. 



New fishes collected off the Coast of Alaska and the Adjacen 

 Region southward. By Tarleton H. Bean. From Proc. U. S. 



Nat. Mus. Vol. xiii, pp. 37-45. Issued July i, 1890. The descrip- 

 tion of seventeen new species and four new genera constitute this 

 contribution.

Part ii, June, 1890. 84 pp. 4to, with thirty-seven plates, the first 

 twenty-four by the late Dr. Kellogg, the thirteen following much 

 better ones by George Hanson, but all lacking in the details essen- 

 tial to botanical drawings.

*Mr. Greene identifies Q. Ransomi Kell. with Q. Douglassi, instead of putting it 

 under Q. lobata as in the Botany of California. In this he is certainly correct, for 

 not only did Dr. Kellogg so state in the note referred to, but in the annotated' list 

 of his species published in Bull. Cal. Acad, which was prepared in constant 

 consultation with him, the statement is reiterated. Mr Greene has however made it 

 sufficiently evident, both by text and drawing, that Dr. Kellogg did not distin- 

 guish, if indeed they can always be discriminated, the northern Q. Douslasii from 

 the more or less evergreen white oak of the southern part of the State. It is 

 more than probable, ju.iging from its locality (Tcjon Pass south of Tehachapi) tluit
