56 Contributions from the Gray Herbarium 
Corropsis Strtumanu (Gray) Blake, Proc. Am. Acad. xlix. 342 
(1913). A considerable range extension for this species is afforded 
by specimens in the British Museum collected by M. E. Jones at 
Pasadena, California, 2 May 1882. 
Cornocarpus pissectus (Benth.) Blake, Proc. Am. Acad. xlix. 
344 (1913). This species (Acoma dissecta Benth. ! Bot. Sulph. 29, 
t. 17 (1844)) was originally described as collected at Cape San 
Lucas, at the southernmost extremity of Lower California. Of 
the two type sheets in the Kew Herbarium one is marked Bay of 
Magdalena, Hinds, 1841, the other Magdalena Bay, so that the 
record of locality in the original description seems to be based on 
an error. The other specimens I have examined, collected by 
_ Brandegee in 1889 (Gray Herb.) and by Anthony in 1897 (hb. Kew) 
are all from Magdalena Island. The species has a distinct and 
fairly tall stem, which is not well indicated in Bentham’s plate. 
Tonalanthus aurantiacus Brandeg.! Univ. Calif. Pub. Bot. vi. 
75 (1914); Cockerell, Torreya xv. 70-71, fig. 1 (1915). — Purpus 
7002, type of the only species of this proposed new genus, from 
Sierra de Tonala, Chiapas, is identical with CALEA MEGACEPHALA 
Rob. & Greenm. Proc. Am. Acad. xxxii. 21 (1896). There seem to 
be no characters to justify the generic separation of the species.
