A large specimen which must have been fully a meter in length 

 when alive, and which is 15 mm. in width after preservation, was 

 collected by Dr. D. IS. Jordan at Santa Barbara, California. 



The species was also collected by the Albatross off central Cali- 

 fornia (Sta. 3-J03, 36° 48' N. Lat., 121° 53' W. Long.) in 138 fms., 

 brown mud. Bottom temperature 45° F. One specimen of medium 

 size. 



Besides its range on the Pacific coast, at least from San Pedro, 

 California, to southern Alaska, the species is found in the Mediter- 

 ranean, on the coasts of Great Britain, Madeira, Greenland, the 

 northeastern coast of America, and in other localities. 



33. Cerebratulus signatus, sp. nov. 

 PI. 4, figs. 42, 43. 



Body of moderate size, rather thick and short after preservation, 

 of greatest diameter just behind mouth and ta})ering gradually 

 toward narrow posterior extremity (PI. 4, fig 42) ; lateral margins 

 very thin in intestinal region, continuing foi-\vard as sharp ridges as 

 far as posterior ends of cephalic furrows; head not demarcated 

 from body after preservation, acutely pointed anteriorly and flat- 

 tened dorso-ventrally ; cephalic furrows short, but deep and con- 

 spicuous (PI. 4, fig. 43) ; mouth small, situated as far back as pos- 

 terior ends of ceplialic furrows. 



Length of single preserved specimen 55 mm.; width 6 mm. 



Color. — Indications of characteristic markings are still visible on 

 the preserved specimen, although the coloring in life is unknown. 

 As shown in PI. 4, fig. 42, there is a conspicuous Tiarrow band of 

 dark cohn- (brown in specimen) extending whole length of body in 

 the median dorsal line. This dark band does not extend forward 

 quite to tip of snout and is interrupted near posterior extremity of 

 body. On each dorso-lateral surface of body is a series of nan-ow 

 transverse markings of similar l)rovvn color, placed side by side and 

 situated about midway between lateral margins of body and dorso- 

 median bainl. It is uncertain whether these markings extend to 

 posterior end of body, for they are visible only in the anterior half 

 of this specimen. Ventral surface is probably without definite 

 markings.
