Descn2)tion. — Test composed of a straight or more often slightly 

 arcuate series of chambers closely joined to one another, chambers 

 evenl}' tapering at either end or slightly oval; wall of fine sand and 

 a reddish brown cement, slightly roughened on the exterior, interior 

 smooth; aperture small, rounded, at the end of the chamber, without 

 a definite neck; color dark brick red. 



Length up to 3.5 mm. 



Distributio7i. — ^This species originally described from the Pliilippine 

 region seems to be present in the Gulf of Mexico and the Caribbean 

 Sea. I have had it from the five stations here given and also have 

 found specimens in the Goes collection labeled by him, ' ' H. ovicnla, 

 forma sphaeriierus" showing that he had noted the difference between 

 this and other species. The very dark red color of the specimens of 

 the Gulf of Mexico and Caribbean will distinguish them from other 

 species of the genus in those areas. It may be found to be distinct 

 from the Philippine species.
