Diagn. — Snout crestless, but furnished with irregular rows ol 

 small spines. 



Descr. — I have seen only a female example, which the Paris 

 Museum received from Leyden, under the name of Syngn. mi- 

 crognathus, Kuhl et V. Hasselt. Under the same appellation 

 I have received three specimens from Leyden, which belong to a 

 totally distinct genus*. 



The short, thick, irregular snout, spinous on its dorsal aspect, 

 is one-third of the length of the head. Eyes large, and the very 

 rough-bordered orbits rise suddenly and are closely pressed to- 

 gether so that the forehead is very narrow. Occipital crest 

 sharply ridged and toothed. A line standing out in relief extends 

 from the orbits to the occiput. Gill-cover roundish, bulging, 

 rough, and divided into two dissimilar parts by a prominent line. 

 A toothed crest on the nape and breast-shield. Between the 

 breast-ring and the dorsal fin there are 14 rings, or 15 if the 

 anal ring be added. The dorsal is supported by 7 rings. The 

 tail, which is not quite the length of the body, has 40 rings. 

 The lateral line reaches to the anal ring, and the upper angular 

 edge of the tail is continued from the termination of the lateral 

 line to the first ring of the dorsal.

* The Syngn. micrognathus of the Leyden Museum, represented by 

 these three specimens, is one with the S. compressus of Kuhl and Van 

 Hasselt ; and the manuscript name of Typhlus Goudoti of Bibron is a 

 synonym thereof. This latter I prefer for the specific designation.
