HISTORY OF THE FISHES OF MASSACHUSETTS. 157 



inclined forwards. Mouth and throat greatly projecting. Length of head about one 

 third the length of body ; its depth through eyes about three fifths the greatest depth. 

 Eyes rather large, situated about midway between top of head and throat ; their diame- 

 ter about three fifths of the distance above them. Nostrils double, in front of eye ; the 

 anterior nearly beneath the posterior. Jaws about equal. Scales wanting. Lateral line 

 with an abrupt curve over pectorals to lateral spot ; thence straight to tail. 



First dorsal commences slightly in front of pectorals. Second ray strongly filamentous ; 

 others somewhat so. Between this and the second dorsal four short but well-defined 

 spines. 



The first ray of the second dorsal is short and spinous ; the next four much longer than 

 the rest, which are of nearly equal length. 



Pectorals quite large, of an elongated oval shape. 



Ventrals somewhat filamentous, with an almost concealed spine at base. 



Anal preceded at some distance by two spines, of which the anterior is the smaller ; 

 another spine at origin of the fin. Along its base, as at that of the dorsal, are spines 

 corresponding in number to the rays, their points directed backward. 



Caudal fan-shaped and deeply emargiuate. 



Length, two inches. 



The fin rays are as follows : D. 8 - 1 - 22. P. 9. V. 4. A. 2 - 1 - 17. C. 20. 



Remarks. Although in many respects this fish resembles the A. capillaris, I think it 

 must be distinct, and if so, the unimaculatus of Batchelder. His specimen was taken at 

 Saco, Maine. The only specimen I have seen was caught in a scoop-net at one of the 

 bridges leading to South Boston, in October, 1847, and sent to Dr. Gould, who kindly 

 transmitted it to me.
