2 AMERICAN MUSEUM NOVITATES [No. 74 



cylindrical shells of foraminifera. Hyalinoecia tubicola (Mtiller) Malmgren 

 subspecies stricta Moore, like other species of this genus, builds a quill- 

 like tube of very hard, tough chitin, slightly narrower at one end than at 

 the other, open at both ends, and slightly curved. Rarely ccelenterates 

 or barnacles are attached to the surface. Small tubes are translucent 

 white, older ones are brown. 



As stated above, many of the Onuphis were in the tubes I have 

 described as typical. Others had attached bits of Hyalinoecia tubes to the 

 outside of their own. In other cases the Onuphis was living inside a 

 Hyalinoecia tube of which one side had broken away and the break was 

 repaired with characteristic Onuphis material. Still others were living 

 in complete Hyalinoecia tubes and there was no trace of the character- 

 istic Onuphis tube-material. This occurred often so that I very soon 

 learned that it is not safe to assume that the animal in a Hyalinoecia tube 

 is really Hyalinoecia and not Onuphis. Obviously, Onuphis may con- 

 struct a tube of its own, but it frequently uses instead an empty one of 

 Hyalinoecia .

Through an error in locality labels, Moore first described this 

 species as from Greenland, but he later corrected this and showed that 

 it is really an Alaskan form. In the last of the above references, Moore 

 reports on the study of a number of individuals and concludes that it is a 

 highly variable species whose limits can be accurately ascertained only if 

 a large number are available for study. 



The present collection contains a single specimen lacking the median 

 tentacle and with only a fragment of an elytron left. In many respects 

 it agrees with Moore's description but it does not show cilia on the 

 palps or on the peristomial cirri. The fragment of the elytron is thickly 

 studded with conical spines, but not enough of it is left to enable me 

 to determine whether the papillae described by Moore are present. 

 In view of the similarities between this and Moore's description, I have 

 tentatively located it here.
