slender. Caudal fin narrow, more than f length of head. Second dorsal 

 and anal high. Lateral line disappearing under middle of second dorsal. 

 Color obliterated, traces of a black spot on spinous dorsal. Length of 

 specimen 3 inches. One of Dr. Hoy's types, in very bad condition, exam- 

 ined by us. It has grown soft in weak alcohol, and its remarkable slen- 

 derness of body is perhaps, in part at least, due to this fact. Lake 

 Michigan, in deep water. (Named for A. L. Kumlien, the ornithologist.)

2342. URAMDE.4 GRACILIS (Heckel). 



Head 3^; depth 5. D.VHI, 16; A. 12. Body rather slender, fusiform; 

 preopercular spine moderate, concealed. Mouth rather large, the maxil- 

 lary reaching to the pupil; pectorals reaching front of anal; ventrals 

 about to vent. Color olivaceous, mottled, upper edge of spinous dorsal 

 red in life. Streams of New England and New York, recorded from tribu- 

 taries of the Connecticut, Lake Champlain, Hudson, Delaware, and Sus- 

 quehanna; commim; probably a variable form, including several of Dr. 

 Girard's nominal species, as Dr. W. O. Ayres vigorously insisted in 184.5, 

 before the latter had been described. {(jracUis, slender.)

* Coitus viscosus is thus characterized : 



Head 3* in length; depth4s. D. VI. 18: A.12; V. T, 3. Body rather stout: mncouspores 

 on head usually numerous. Mouth small; maxillary reaching middle of eye; preopercu- 

 lar spine acute, extremely sill irt, directed obliquplV upward; istlinius rather narrow; 

 flrstdorsal low, slightly conneetvd with Hecond ; ixMtorals slinrlei th.-iii lirud, reaching sec- 

 ond dorsiil. Color olivaciMius, varifg:iTed. tlic spinous dorsal ciliiid \villi orange in life; 

 fins mostly barred. E.astrrii I'eimsylvauia and ^larylaiid, in tributaries of the Schuylkill, 

 Sus(iueliaiina, and Potimiae rivers; not rare, entering caves. 



t Oottus gobioides is tlius described; 



Head 3J; depth 4|. 1). All, 17: A.12. Similar to Uranidea gracilis, bnt larger and 

 more robust, the mouth larut'v. reaching to beyond the line of the pupil, and the pectorals 

 short, not quite reaching ;iiiiil ; iniMiixKularspine stout, curved suddenly upward. Length 

 4 inches. Tributaries of I. akr ( 'li;nii]il;iiu. (Girard.)

Head3i; depth 5^. D. VIU 17; A. 11. Slender, snhfnsiform. Month Mther large, 

 the maxillary extendingto opposite the pupil : i)reoi)(>reiilar spine acute, directed obliquely 

 upwards; isthmus narrow. Fins larger tli;iii in any otlur sjjecies; ]>eetorals reaching
