Xiphiorhynchus Kimblalocki, A New Billfish From The Eocene Of Mississippi With Remarks On The Systematics Of Xiphioid Fishes, Harry L. Fierstine, Shelton P. Applegate
Biological Sciences
Xiphiorhynchus kimblalocki, a new species of extinct billfish from the Eocene of Mississippi, is described. This is the first record of Xiphiorhynchus outside of western Europe, and the material consists of a well-preserved rostrum, three partial vertebrae and two fin spine fragments. Xiphiorhynchus kimblalocki is compared with other living and extinct billfish and appears to be intermediate in morphology between the Xiphiidae and Istiophoridae. Various genera of fossil billfish are critically discussed and we suggest that the Blochiidae, Paleorhynchidae, and the "Cylindracanthus-group" should be placed in Xiphioidei lncertae sedis until better evidence indicates that they are billfish. …

New Taxa In Pectis (Compositae: Pectidinae) From Mexico And The Southwestern United States, David J. Keil
Biological Sciences
This paper is the first of a series of investigations on the systematics of Pectis L., the largest genus in the subtribe Pectidinae of the tribe Helenieae. Pectis consists of about one hundred species of annual or perennial, glandular-dotted, yellow-rayed herbs that are widespread in the warmer parts of the New World. In the present report three previously unrecognized taxa from Mexico and the southwestern United States are described as new, and a new combination also is made
