by them. A. ScOTT, 1905, p. 366, states that this species was found ut a number of stations 

 in Ceylon; a total of ten females and four males is stated to have been caught. No figures are 

 given, so that I did not think it proper to include this form as a s;yTionym. Til. Scott, 1912 a, 

 p. 586, gives this species as coming from Gough Island, lat. 40" 20' S., long. 9*56' W. Two 

 figures which are quite useless for certain identification are given, but no description. This 

 cannot possibly be included as a synonym. 



Nothing definite can be said as to the relation of my species A. Miilleri, Ohlini and nirtn 

 to the female referred by G. S. Bradv to A. oculata. 



Distribution: — Ceylon: Trincomalee (G. S. Brady, 1902 a). \Micther it also occurs 

 at St. Johns (Cruz Bay), Lesser Antilles, I cannot say; it seems rather probably, however, that 

 this identification of G. S. Bhady's is due to a mistake.

Description: — Female: — 



Shell: — Length, 2,0 — 2,26 mm.; length : height about 1,9:1; length : breadth 

 about 2,2 : 1. Seen from the side (fig. 1) it is of about the same type as A. Grrimaldi, 

 but, as is shown by the figures given above, it is somewhat higher relatively. The dorsal and 

 ventral margins are somewhat, though only rather slightly, more decidedly curved than in the 

 species mentioned above. Seen from below (fig. 2) it also has about the same t^'pe 

 as A. Grimaldi; it is only a little broader relatively. Seen from inside: Medial bristles: 

 On the rostrum there are rather numerous, stiff, moderately long bristles; of these the ones 

 that are situated nearest to the anterior margin of the shell are arranged in a rather dense and 

 distinct row running somewhat inside and about parallel to the margin of the shell; the others 

 are scattered. Most of these bristles are subequal, those situated along the anterior margin 

 of the shell are perhaps on the average rather shorter tlian the rest; among the latter, however, 

 a few more or less short bristles are interspersed, especially among those situated farthest in. On 

 the anterior wall of the incisur there are rather numerous scattered moderately long bristles, 

 most of them subequal. There is in addition in the incisur a very dense row of similar bristles, 

 running about parallel to and somewhat inside the ventral margin of the rostrum. Besides these 

 bristles there are in the incisur only a few moderately long scattered bristles. C)n the part just 

 behind the incisur there are also rather numerous scattered bristles; most of these are of about 

 the same type and length as the long bristles on the rostrum, a number of those situated farthest 

 in are very short; on the anterior portion of this part there is often only a very small number 

 of bristles situated farthest in; these are all extremely short. Along the ventral margin of th(>
