Remarks. — The second of thetwo hermaphrodite specimens 

 recorded above measures 63 mm. in length of capitulum by 

 47 mm. in breadth, and the peduncle is 87 mm. long by 

 about 29 mm. in diameter in the middle. These dimensions 

 are considerably greater than those recorded by Annandale, 

 and show that the species reaches a size not exceeded, if it 

 be attained, by any other member of the genus. 



Certain slight differences from Annandale's description 

 are shown by both specimens. The occludent basal angle of 

 the tergum is by no means acute, but, as shown in Annan- 

 dale's figure, clearly obtuse. The apices of both tergum and 

 scutum may be straight or slightly recurved. The median 

 latus (called inframedian and sometimes upper by Annan- 

 dale) is quadrangular, not triangular; its posterior (or 

 carinal) angle does not " dive beneath the carina/' but is 

 broadly truncated, forming a side, the shortest of the four, 

 parallel to the margin of the carina. The apex of the carina 

 is free for a short distance in one specimen, but not in the 

 other ; the roof is bluntly ridged in the middle and flat or 

 faintly concave on each side ; the parietes are very narrow 

 and inflected. The basal half of the carina is straight in one 

 specimen, gently curved in the other. 



The first cirrus has the rami unequal in length, but with 

 about the same number of segments (20 : 21 in one specimen). 

 The penis is laterally compressed in one specimen, as in 

 Annandale's description, but in the other it is swollen; it 

 does not exceed one-half the length of the sixth cirrus. 



Annandale states that this species " would find a place in 

 the genus Calautica as redefined by Pilsbry in 1908." 

 Pilsbry based the separation of Calantiea from Smilium on 

 the fact that in the former genus there is "no plate inter- 

 posed below the tergum between scutum and carina," stating 

 that "in other characters the two groups are almost identical." 

 Presumably, therefore, Annandale's remark was suggested 

 by his impression of the median latus as triangular in form, 

 with its posterior angle overlapped by the carina. As shown 

 above, however, this plate is distinctly quadrilateral, and it 

 is interposed, as clearly as possible, between the scutum and 

 the carina, Scaipellum nudipes is, indeed, well fitted to show 

 that the distinction between Calantiea and Smilium, as defined 

 by Pilsbry, is of little importance (as Pilsbry bin self acknow- 

 ledges), and that Annandale was justified in disregarding- it. 

 Dr. Annandale goes on to say, " In spite of the absence of
