Malacop terygii. 



Fundulus multifasciatus Cuv., Val. From Frederick, Macomb Counij, 

 Grosse Isle, and Oakland County. 



Fundulus* aureus, sp. nov. 



Head flattened, its depth at orbit three-fourtbs interorbital width ; latter one- 

 half the length of head, or one-eighth the total length to end of scales at base 

 of caudal. Eye large, its diameter contained once in advance of it, and one 

 and a half times to opercular border. Mouth terminal, mandible slightly 

 longer. Back flat to middle of its length, then rapidly compressed to caudal. 

 Scales large, with no exposed and ten concealed radii, nine longitudinal, thirty- 

 three transverse series. Greatest depth four and three-quarter times in length 

 from end of muzzle to end of scales. Pectorals not reaching ventrals, norven- 

 trals the vent. Anal originating in advance of dorsal, like the latter, rather 

 short. From base of caudal to anterior base of dorsal equals one- half the 

 length from latter point to end of ossa nasalia. Radii D. 10 C, rounded 16 

 (complete) ; 11 ; V. 6 ; P. 13. Br. 5. Total length two inches. Above uniform 

 light golden brown; below pale yellow, inferior part of opercula silver white ; 

 a brown band extends from the end of the muzzle to the origin of the caudal 

 fin. 



From Grosse Isle ; obtained by Prof. Fox. 



The anterior position of the anal fin allies this to some species which have 

 been separated under the name of Zj/gonectes, for what reason has not yet been 

 explained. A banded species from St. Louis, Mo., has been named Z. zonal us 

 by Agassiz, but as there is no description, it has not entered the zoological 

 record. 



Melannra 1 i m i Agass. Hydrargyra Kirt. 

 Flint River, Grosse Isle and Oakland Co. 



Esox cy p h o, sp. nov. 



Profile steeply descending ; muzzle slightly concave. Frontal concavity 

 short, strongly marked, as wide as the superciliary plane on each side of it ; 

 eye contained six and one-half times in length of head, a little less than frontal 

 width ; pupil opposite extremity of maxillary. Latter appressed posteriorly, 

 so as to give a shorter cranial diameter than at the middle of the muzzle. 

 Head contained two and two-fifth times in length to end of caudal. Buccal 

 and opercular scales equal, similar to those on middle of body, smaller than 

 those near anal fin. On body, IS 110 12. Dorsal region elevated, broad; 

 caudal peduncle thick, its length equal from eye to posterior edge of oper- 

 culum. Emargination of caudal two-fifths length of the fin. From symphysis 

 mandibuli to anterior margin of orbit 1 in. ; from latter point to edge of oper- 

 culum 1 in. 5 lin. ; from last point to origin of ventrals 1 in. 8 lin. ; from same 



* Fundulus s c i a d i c u s, sp. nov., was brought by Dr. W. A. Hammond from the Nebraska or 

 Platte River, and presented to the Academy. The lorm is short and stout, the scales large the 

 Ads small and the anal originating a little in advance of the dorsal. Length of head 85 times to 

 biise of tail; eye 3 times in length of head, once in front of orbit, and one and two third timrj 

 between supercilia. Base of caudal to anterior base of dorsal a little less thm half from latter 10 

 end of premaxillary. From base of caudal to base of ventrals equal from hitter to opposite ante- 

 rior margin of pupil. Thirteen longitudinal, thirty-nine transverse series of scales. I), prolonged 

 a little beyond anal 10. A. 12. V. 8. Largest specimen two inches in length, many smaller. 



Above olive slate color; below, the caudal peduncle and opercula brownish yelbw. No spole 

 or linee.
