234 PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. OEXERA OF THE SCOr.OPC:i\l>REI.L.II>^. By J. A. RYDER. There are two forms of this group ; the first has the body very slender, tapering-anteriorly, with the eyes or stemmata placed on the upper sur-face of the narrow, elongate head; the second form has a broader, more robust body of nearly uniform width anteriorly and posteriorly, with the eyes or stemmata at the sides of the head and not visible from above, the head itself being nearly circular or subquadrate in outliue from above. The first is the type to which we may assign the old designa-tion of ScoJopendrella originally i)roposed for it by Gervais; the second, of which Newport's species becomes the type, may be distinguished generically from the first as pointed out above, under the name of SciitigereUa. Tlie latter form is also distinguished from the first by the much greater development of the basal appendages of the legs. IScolopendreUa comprehends : tS. notocantha Gervais. 8. microcolpa Muhr. Scutigerella comprehends: 8. immaculata Newport. 8. graticv Kyder. The literature of the subject has been fully cited by me in a paper entitled The 8tn(ctur€, Affinities, and 8j)ecies of ScoIojmidrcUa, iu Proc. A lilST OF THE SPECIES OF FISHES KECOROED AS OCCURRINQ IIV THE OLTf.F OF MEXICO. By O. BROWN OOODE and TARI>ETO]V H. BEAN. For the convenience of collectors in the Gulf of Mexico we have pre-pared the following list of fishes recorded as occurring in its waters. Of the species marked by an asterisk there are specimens in the National Museum from this region. We have not inquired into the validity of the other species, but have given them under the names by which they are cited in tlie works of Giiuther, Cuvier & Valenciennes, Girard, and other authorities, preferring to leave their nomenclature unchanged until studies have been made upon specimens. Nearly 300 species are enumerated iu this list and several unciescribed
