GORDIACEA FROM THE COPE COLLECTION. 



THOS. II. MONTGOMERY, JR. 



AT his death Prof. Edward D. Cope left to the Philadelphia 

 Academy of Natural Sciences, among other alcoholic collec- 

 tions, a few specimens of Gordiacea. Among them is a new 

 species, while the others are interesting from the standpoint 

 of geographical distribution. 



1. Gordins aquaticus (Linn). One $ from Haines Falls, Cats- 

 kills, New York, U. S. A. This specimen is a typical one of 

 this species, and is particularly interesting as coming from such 

 an eastern locality of the United States ; previous specimens I 

 have described only from Mexico and California, while all others 

 of the species seen by me from the eastern part of the continent 

 belonged to the following subspecies : 



2. G. aqtiaticus robitstus (Leidy). Three $ $ from Austin, 

 Texas, the first record from this State. 



3. Paragordius varius (Leidy). One $ from the same locality. 



4. Chordodes occidcntalis (Montg.). One $ from Texas, taken 

 from the abdomen of a large grasshopper. 



5. C. CameranoniSy n. sp. One $ from the West Coast, 

 " Mazatlan or Panama." This type is in the collection of the 

 Philadelphia Academy of Natural Sciences. 



Form. --Body dorso-vent rally flattened, with slight median 

 grooves. Anterior third of the body gradually tapering to a 

 point, but the extreme end of the head truncated. Posterior 

 end also attenuated, but less so than head ; rounded terminally. 

 A post-cloacal ventral groove is in the males of most species of 

 the genus. 



Cuticle.- -Three main kinds of cuticular processes may be 

 distinguished : 



(i) The most abundant are low tubercles, which, on surface 

 view (Fig. 5), appear more or less rounded or oval in outline, 

 less frequently notched at one side, or sickle-shaped. While on
