KEVISION OF THE FISH FAMILY LIPARIDAE 153 



Relationships.— G. minytremus differs from certain species of Care- 

 produs solely in the reduced gill slit. See discussion of the relation- 

 ships of the genera. 



Description of type. — Head 5.5 in length without caudal. Eye 3.3 

 in head; disk 2.2 Pectoral 25; caudal 14. 



Body rather slender and elongate as in Careproctus edenes; abdomen 

 distorted with large eggs. Head small, depressed, a little deeper 

 than wide; depth 7, width 8 in length without caudal; cheeks nearly 

 vertical; occiput not swollen; interiorbital flat, internostril 3.2 in the 

 head. Mouth small, terminal, with little lateral cleft; maxillary 

 reaching a vertical from slightly behind the front of the eye. Teeth 

 simple, slender, concial, inner teeth prominent, much larger than 

 outer teeth ; about five widely spaced oblique rows in the half of each 

 jaw. Snout short, 3 in the head, rising abruptly from the mouth. 

 Nostril single, the tube with a raised rim in front. Eye large, black; 

 pupil round. Gill slit a minute pore that will not admit a large 

 dissecting needle, high up above the base of pectoral fin. Tip of

opercular arm buried beneath skin. One suprabranchial pore present, 

 above and behind the gill slit; upper pores on the snout high; nearly 

 between the nostrils. Pyloric coeca unknown. No prickles. 



Origin of dorsal fin back of the middle of the pectoral; the anterior 

 rays not distinctly seen but not buried in thick tissue. Caudal 

 truncate, of very slender rays, connected for half its length to the 

 anal, the dorsal and anal connections with the caudal gradual. 

 Pectoral fin not notched, with the upper edge on a level with the lower 

 margin of the orbit, of about 25 rays which increase gradually in 

 length. Disk well formed, oval ; snout to disk 8.5 in the length without 

 caudal. Vent close to the disk; tip of mandible to vent 4.3 in length 

 without caudal. 



Color light brown; peritoneum white, dotted with browTi. 



Synopsis. — Pectoral 25; caudal 14. Body rather slender and elon- 

 gate; head 5.5 in length without caudal. Eye 3.3 in head; disk 2.2. 

 Teeth simple, slender and conical. Eye large, black; pupil round. 

 Gill slit leduced to a minute pore high up above the base of the pecto- 

 ral fin. One suprabranchial pore evident. Pectoral fin apparently
