Laganum solidum de Meij. 



Laganum solidum de Meijere, 1904. Ech. Siboga-Exp., p. 121 ; Plate 1, Figs. 

 64, 66. 



A number of bare tests, collected at several localities, differ from both the pre- 

 ceding and following species, in the far more numerous primary tubercles of the 

 abactinal surface. They answer very nearly to the description and figures of 

 solidum, and may, for the present at least, be referred to that species.

Laganum strigatum A. Ag. and Clark. 



This species resembles fudsiyama in the short, narrow, open petals, the very 

 narrow poriferous zones, and the moderately coarse tuberculation of the test. 

 But it is easily distinguished from that species by the flatness of the test, the height 

 of which rarely exceeds .20 of the long diameter; the distinctly visible sutures 

 between the plates abactinally as well as actinally ; and the color, which is pur- 

 plish-gray or dull brown, with the sutures more or less plainly indicated by darker 

 lines. There are usually five, but sometimes only four, genital pores. The anal 

 opening is near the posterior margin of the test. A typical example is 30 x 29 

 mm. and only 6 mm. high.
