在北美，特别是在马萨诸塞州的伍兹霍尔，我们发现了一种表面上与格兰蒂亚相似的海绵。许多年前，有人漫不经心地认为它确实是那个属。几。这些时刻足以说明，这并非易事。Grantia Fleming 1828具有明显的真皮皮层，包含切线放置的辐射针状体的特殊皮质骨架。美国人所谓的格兰蒂亚没有这样的大脑皮层。我们的海绵不是一个未知的属，而是一个多世纪以来海绵学生所熟悉的属；1821年，格雷将其命名为八cypha。对伍兹霍尔“Sycon”海绵物种的初步鉴定可能是。命名为8cypha (8pongia) coronata （Ellis and Solander 1786）。
North America, and particularly at Woods Hole, Massachusetts, we have a sponge that bears a superficial resemblance to Grantia. Many years ago some one carelessly assumed that it was indeed that genus. A few. moments are enough to sh'ow that such is not the ease. Grantia Fleming 1828 has a distinct dermal cortex containing a special cortical skeleton of tangentially placed radiate spicules. The American socalled Grantia does not have such a cortex. Ours is no unknown genus, b~ t one that has been familiar to students of sponges for over a century; it was named 8cypha by Gray in 1821. A tentative identification as to species of the Woods Hole" Sycon" sponge may be. given as 8cypha (8pongia) coronata (Ellis and Solander 1786).
