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.

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
