Fusulinids occur in great abundance throughout the interval of Pennsylvanian sediments in the Joyita Hills. A new genus Parafusulinella is described with two new species, P. propria from the Joyita Hills, and P. mexicana from the Boca Grande Mountains of northwestern Mexico. Other new species described from the Joyita Hills include Plectofusulina rotunda, P. coelocamara, P. fusiformis, Beedeina joyitaensis, Wedekindellina elongata, W. alveolata, Triticites riograndensis, and T. liosepta. The stratigraphic occurrence of the fusulinids, their biozones and paleoecological significance have been discussed in Part I of this study. Additional discussion concerning stratigraphy, faunal assemblages, taxonomy, systematic descriptions, and phylogeny follows. All specimens and types are filed in the Texaco Inc. paleontological collections.
