the sides; the vomerine and palatine bones have a contiuuoiis band of 

 tt'eth, narrowest on the vomer; the tongue is hard, cartilaginous, and 

 destitute of teeth. The cleft of the mouth reaches only to the Tertical 

 from the nostril; the eye is small. The pectoral is rounded and small, its 

 length being \ of the total; the ventrals are slightly jiointed, and, as in 

 all the species of the genus, composed of 1 spine, hidden in the skin, 

 and 4 soft rays; they are inserted iunnediately behind the vertical from 

 the pectoral, which they equal in length; they can be received in a shal- 

 low groove on the abdomen. The distance between the dorsal and the 

 disk is "ih in the length of the latter; the dorsal is low, and envelopedfin 

 a thick membrane. The caudal is truncated when stretched out. The 

 anal is very similar to the dorsal, and its origin and termination fall ver- 

 tically below those of the latter. The scales are minute, and can be per- 

 ceived only by the aid of a magnifier; they are embedded in pore-like 

 cavities. (Giinther: description of type of Echeneis scutata.) Tropical 

 seas; rare; recorded by Dr. Liitkeu from 10"^ N., 39^ W. (Coll. Capt. V. 

 Hygom) from a dolphin; not seen by us. (aiiatralis, southern.)
