This small species has some resemblance to the last in 

 the colours of the body, but it is a more slender fish, and 

 the nape is clothed forward to the eyes with scales, nearly 

 as large as those of the body, which are of moderate size. 

 There are no scales on the gill-covers, or rest of the head. 

 The basal grooves are few and parallel, the free edge of 

 the scale toothed. The length of the head is twice its 

 height, and forms one-fourth of the total length of the 

 fish, caudal included. The under jaw is a little more 

 prominent than the upper one. The jaw teeth are disposed 

 in broad, very close, villiform plates, with an outer row of 

 stouter and more widely set teeth, but scarcely taller. 

 There are no distinct canines in the middle of the lower 

 jaw, or elsewhere, and none of the teeth can be clearly seen 

 without the aid of a lens. The gill cover is convex. 

 Three mucigenous lines diverge from the upper lip, a little 

 above the angle of the mouth, one to run immediately 

 beneath the eye, another to cross the middle of the cheek, 

 and a third to traverse the lower part of the cheek. A 

 fourth line runs from the chin along the limb of the lower 

 jaw and the interoperculum, and ascends the vertical 

 limb of the preoperculum. A similar line skirts the tem- 

 poral groove, and two diverge at a right angle on the gill- 

 cover. Open pores exist on the upper border of the orbit 

 and vertical limb of the preoperculum. The general 

 colours of the specimens in spirits are honey-yellow, 

 marbled and spotted with umber and blackish brown, and 

 minute white specks exist in longitudinal rows along the 

 lower part of the sides. A dark mark is jilaced on the 

 tail, close to the base of the caudal fin, and there are 

 many dark dots on the snout. The cheeks have a bright 

 purplish hue, with numerous whitish specks. The basal 

 halves of the jjectorals are also studded with white specks. 

 There are four rows of dark dots in the first dorsal, and 

 six rows on the second dorsal and caudal. The anal is 

 dark on the border, but unspotted, and there are no marks 

 on the ventrals. Length of the specimen, \^ inch.

 This goby has much resemblance in general form to the 



preceding one, and, like it, belongs to the division which 

 is characterised by the negative characters of the want of 

 canine teeth, the absence of free simple rays in the pec- 

 torals, or of any other remarkable peculiarity in the fins. 

 The snout is very short and gibbous, the eyes rather large, 

 and nearly touching above, and the cheeks are not swollen. 

 The teeth are in villiform bauds, tapering off nearly to a 

 single series towards the corners of the mouth, but having 

 considerable breadth at the symphysis, from the addition, 

 as it were, of several rows exterior to the general line of 

 the dental surface. The exterior ones are a very little 

 stouter than the rest, and all are slightly incurved, but 

 there are no canines. The eyes are very prominent, and 

 the short snout is suddenly rounded off. The preorbitar 

 lip is rather full, but it is even, and in no wise lobed or 

 notched, as in Perioplit/ialmus,\\\nch this fish much resem- 

 bles in the face. The scales of the cranium terminate by 

 a rounded outline, which just touches the orbits. The 

 snout, the whole of the cheeks, gill-plates and membranes 

 are scaleless. Bright yellow muciferous lines branch on 

 the cheek, and traverse the temporal furrow. There are 

 open pores on the disk of the preoperculum, in the tem- 

 poral furrow, on the nape, and other parts of the head. 

 The lengths of the head and caudal fin are about equal, 

 and each forms one-fifth of the length of the whole 

 fish. 



The pectoral is semi-elliptical, or more rounded when 

 very fully extended. Its membrane is very delicate, and 

 readily disappears ; but in our most perfect specimens, only 

 the tips of the upper rays are free. The uppermost ray 

 alone is simple. The first and second rays of the first 

 dorsal are longer than the rest. The last ray of tlie second 

 dorsal and of the anal is divided to the base. The caudal 

 is rounded. 



The scales of the body are rather large, and very regu- 

 larly placed. Each is five sided: having the lateral sides 

 straight and parallel, the base undulated, so as to produce 

 a central rounded lobe, and the two free or posterior sides 

 meeting in an acute angle, with the apex more or less blunt. 

 These free sides are strongly and regularly toothed. About 

 twelve fine fan-like lines run from near the posterior tip lo 

 the basal lobe. There are twenty-six scales in a row 

 between the gill-opening and the caudal fin. 



The general colour of the specimens in spirits is honey- 

 yellow. The sides are marked by brownish black inter- 

 rupted lines, which in the upper parts are slender and 

 approximated. The lowest two, being on a level with the 

 lower half of the pectorals, are composed of a series of 

 seven or eight oblong, rectangular spots. The fine upper 

 lines are most numerous at the shoulders of the fish, pos- 

 teriorly they are reduced to about four; between them 

 there is an equal number of rows of very minute white 

 specks. On the caudal and pectorals there are five or six 

 dark transverse lines, alternating with an equal number of 

 white ones. On the dorsals and the anal there are also 

 alternate black and fine white lines, slightly oblique, and 

 inteiTupted by the rays. The mucigenous fines on the 

 cheeks are bright yellow, the rest of the head looks jiur- 

 plish, but the colour appears to be nearly faded away in 

 our specimens. The specimen which is figured had the
