134 ADDENDA TO MUREX. 



Y. MONACHUS, Crosse. 



This Japanese species which I have included in Ocinebra (ante, 

 p. 127), has certain resemblances to Vilnluria and may possibly 

 belong to the group. 



ADDENDA TO MUREX. 



M. (TRIBULUS) TRYONI, Hidalgo. PI. 70, fig. 427. 



Varices three, compressed, those of the body-whorl with three 

 short, sharp spines, on the spire a single spine upon each ; a spine 

 on the canal below each varix ; canal moderate in length, straight ; 

 whorls seven, the two first smooth, the others with eight or nine 

 very small, narrow longitudinal ribs crossed by numerous revolv- 

 ing lines forming tubercles at the intersections. Color whitish. 



Length, 28 mill. 



Lesser Antilles, at great depths. 



For the above name and description, together with the speci- 

 men figured, 1 am indebted to Mr. J. G. Hidalgo, who obligingly 

 forwarded them to me with the request that the publication 

 thereof should be made in the " Manual." The shell, which is 

 perhaps not adult, belongs to the same group as M. recurwrostris, 

 but differs from all the other species in the great number and 

 relatively little prominence of the riblets between the varices. 



I am indebted to Mr. Hidalgo also for the following notes of 

 locality : 



M. BEATJI, Petit, M. CABRITTI, Bernard! , M. HIDALGOI, Crosse, 

 and M. PAZT, Crosse, have all been dredged together in the 

 waters of the Lesser Antilles. 



' M. CAPUCINUS, Chemn. In describing this species I gave the 

 locality Philippines as doubtful. It certainly is found there and 

 exists in all the Madrid collections made at the islands by the 

 employe's of the Spanish administration. Mr. Hidalgo possesses 

 specimens collected living at Zamboanga, Island of Mindanao.
