CRYPTOTREMA CORALLINUM Gilbert. 



One specimen, 134 mm. long, from station 4420, near San Nicolas 

 Island, depth 32 or 33 fathoms. 



The teeth have been inadequately described in the species. In the 

 front of each jaw is a close-set series of strong conical teeth, the 

 series continued on the lateral margins of the jaws and the teeth 

 there greatly decreasing in size. Behind the outer series is a rather 

 broad patch of short vilhform teeth, which are confined to the 

 anterior part of the jaw, the patch in the mandible smaller than that 

 in the maxillary. A single more or less irregular series of small 

 conical teeth on the vomer and the contiguous part of the palatines, 

 the latter with only two or three of the teeth on its extreme anterior 

 portion. 



In the specimen before us the diameter of the eye is slightly less 

 than the length of the snout, and is contained 4J to 4J times in the 

 length of the head. The longest pectoral rays are below the middle 

 of the fin, but the lowermost rays are progressively shortened. The 

 black blotches on sides are formed as local intensifications of brownish 

 bars which descend from the back. Each of the blotches is forked 

 indistinctly, forming an inverted V. 



EMBRYX PARALLELUS, new species. 

 Plate 19, fig. 16. 



Type-specimen. — Cat. No. 75818, U.S.N.M., 387 mm. long, from 

 station 4514, Monterey Bay, depth 394 to 406 fathoms. 



Closely related to E. crassilabris, characterized by the parallel, 

 nearly vertical sides of head, the thickened lips, the uniserial pre- 

 maxillary teeth, and the dark coloration. From crassilabris it 

 differs principally in the much broader head, and the more extensive 

 scaling of the sides of the head. In crassilabris the greatest width of 

 head is a trifle more than one-third the length of the head; in pardi- 

 lelus it is one-half that length. 



Body very slender, the depth 14.3 times in the total length. Head 

 with nearly vertical parallel sides, of nearly uniform width to the 

 base of the snout, the outline of which is broadly rounded, seen from 

 above. Lips and adjacent tissues soft and fleshy. Lower jaw 

 included, shutting wholly inside the premaxillary teeth. Maxillary 

 reaching vertical from middle of eye. Eye less than length of snout, 

 5.8 times in length of head. Premaxillary teeth cardiform, close 

 set, in a single series, the teeth diminishing slightly laterally, the 

 series short, extending but little more than half distance to angle of 

 mouth. Mandibular teeth anteriorly in a broad band, the anterior 

 and posterior series obviously enlarged, the band abruptly constricted 

 at the middle of the side of the jaw and continued a short distance
