(2) SquiUa affini'sy Berthold. 



Chusan (10-14 fatli.) ; Kowlson Bay (Hong Kong), Holo- 

 tliuria Bank (China Sea) (38-52 f'ath.). 



The specimens from Kowlson Bay and Holothuria Bank 

 closely resemble the specimen named gracilis by Miers in the 

 distribution of the patches of black pigment upon the segments 

 of the abdomen and on the telson, as also in having the telson 

 somewhat narrower than appears to be normally the case in 

 Sq. affinis, and its spines longer. They resemble the typical 

 form, however, in having only four or five spines on the 

 raptorial limbs, and not six or seven, as in the example of 

 gracilis. The specimens in question thus appear to be inter- 

 mediate in characters between gracilis a.\\^ affiais, from which 

 we may conclude that the former can scarcely be permitted to 

 rank as a distinct variety. 



(3) Pseudosquilla oculata (Brulld). 

 A single example from Macclesfield Bank (China Sea). 



(4) Pseudosquilla ciliata (Fabr.). 

 Three young examples from the Arafura Sea. 



(5) Gonodactylus chiragra (Fabr.). 



Baudin Island, Troughton Island, Damma Island, Baleine 

 Bank (15-20 fath.), Amboina Bay, Arafura Sea, Macclesfield 

 Bank (32 fath.). 



A large number of specimens. 



I doubtfully refer to this species a semi-larval form, 

 measuring 9 millim. long, from Baleine Bank, which differs 

 from the adult in having only a single median crest upon the 

 telson. 



(6) Oonodactylus graphurus, Miers. 



N.W. Australia (20 fath.) ; Baudin Island (8-15 fath.) ; 

 Baleine Bank, N.W. Australia (15-20 fath.); Arafura Sea; 

 Holothuria Bank, China Sea (15-24 fath.) . 



A great number of examples. 



The Squillidffi in the British Museum included by 

 Mr. Miers under this head contained examples of genuine 

 graphurus and others which have subsequently been made 

 into a distinct species, G. glaber (erroneously &\>Q\t glabrous) ^ 

 by Brooks. Still later Dr. de Man has united the two again ; 

 but since the dorsal grooves characteristic of graphurus are 

 well marked, without signs of failing, in all the adult speci-
