. Annals of the Carnegie Museum. Carnegie Museum; Carnegie Museum of Natural History; Natural history. Starks: ncAi, Sirvev Anour San Juan Islands. 179 aiitrriorU, and with a wrll (l('\i'l()i)(_'(l knoh in Iroiit, which closes entirt'U- in front of the prcniaxiUary teeth, and parti>- in front of the ujiiier lip. The preniaxillar\- teeth are in very narrow bands, but in more tlian one series at the side. Anteriorh' the band curves inwardly very strongly, and forms a deep notch; the curve is greater and the notch is much deeper than in Scbaslodes saxicola. The vomer and the front of the palatines ha\e a very few fine teeth, much finer and fewer than in Scbaslodes saxicola ; and their presence is rather diflicult to detect. The interorbital space is considerably more deeply concave; it is without ridges, and its width, including the scaly rim that pro- jects over the eye, and measured just behind the preocular si)ine, is contained in the postocular part of the head; the bone is only in the same space. The ocu- lar ridges, though rather high, rise very gradually from the interorbital space. The ocular and tym- panic spines are sharp, but not at all slender, and are very much larger and higher from their base than in Sebastodes saxicola. The preocular spines extend outward over the eye much more; the width of the interorbilal (bone only) just behind them is two-thirds of the interorbital width across the tips of the spines. Xo supraocular spine is present. The occipital ridges are very high and sharp, shorter, higher, much more curved as viewed in profile, and the space between them much deeper than in Sebas- todes saxicola; the ridges end behind in rather sharp, but low spines. The preorbital plate is armed below with two sharp angles, but these are not hooked backwards as sharp spines as is the case in Sebasto- des saxicola. The suborbital ring is very narrow, not wider than the first dorsal spine, and narrow^er even than in Sebastodes saxicola.
